 |----------------------------------------------------------------------------------------------------------------------------|
 |  [Installation and Updates][installation docs] - [Documentation and Tutorials][docs home] - [Bug Reports][github issues] - [Contributing][contributing docs]  | 
 
-# Installation
+</div>
 
-To get started with Invoke, [Download the Installer](https://www.invoke.com/downloads).
+## Quick Start
 
-For detailed step by step instructions, or for instructions on manual/docker installations, visit our documentation on [Installation and Updates][installation docs]
+1. Download and unzip the installer from the bottom of the [latest release][latest release link].
+2. Run the installer script.
 
+   - **Windows**: Double-click on the `install.bat` script.
+   - **macOS**: Open a Terminal window, drag the file `install.sh` from Finder into the Terminal, and press enter.
+   - **Linux**: Run `install.sh`.
+
+3. When prompted, enter a location for the install and select your GPU type.
+4. Once the install finishes, find the directory you selected during install. The default location is `C:\Users\Username\invokeai` for Windows or `~/invokeai` for Linux/macOS.
+5. Run the launcher script (`invoke.bat` for Windows, `invoke.sh` for macOS and Linux) the same way you ran the installer script in step 2.
+6. Select option 1 to start the application. Once it starts up, open your browser and go to <http://localhost:9090>.
+7. Open the model manager tab to install a starter model and then you'll be ready to generate.
+
+More detail, including hardware requirements and manual install instructions, are available in the [installation documentation][installation docs].
+
+## Docker Container
+
+We publish official container images in Github Container Registry: https://github.com/invoke-ai/InvokeAI/pkgs/container/invokeai. Both CUDA and ROCm images are available. Check the above link for relevant tags.
+
+> [!IMPORTANT]
+> Ensure that Docker is set up to use the GPU. Refer to [NVIDIA][nvidia docker docs] or [AMD][amd docker docs] documentation.
+
+### Generate!
+
+Run the container, modifying the command as necessary:
+
+```bash
+docker run --runtime=nvidia --gpus=all --publish 9090:9090 ghcr.io/invoke-ai/invokeai
+```
+
+Then open `http://localhost:9090` and install some models using the Model Manager tab to begin generating.
+
+For ROCm, add `--device /dev/kfd --device /dev/dri` to the `docker run` command.
+
+### Persist your data
+
+You will likely want to persist your workspace outside of the container. Use the `--volume /home/myuser/invokeai:/invokeai` flag to mount some local directory (using its **absolute** path) to the `/invokeai` path inside the container. Your generated images and models will reside there. You can use this directory with other InvokeAI installations, or switch between runtime directories as needed.
+
+### DIY
+
+Build your own image and customize the environment to match your needs using our `docker-compose` stack. See [README.md](./docker/README.md) in the [docker](./docker) directory.

 # Release Process
 
-The Invoke application is published as a python package on [PyPI]. This includes both a source distribution and built distribution (a wheel).
+The app is published in twice, in different build formats.
 
-Most users install it with the [Launcher](https://github.com/invoke-ai/launcher/), others with `pip`.

-## Broad Strokes

-- Merge all changes and bump the version in the codebase.
-- Tag the release commit.
-- Wait for the release workflow to complete.
-- Approve the PyPI publish jobs.
-- Write GH release notes.
+- A [PyPI] distribution. This includes both a source distribution and built distribution (a wheel). Users install with `pip install invokeai`. The updater uses this build.
+- An installer on the [InvokeAI Releases Page]. This is a zip file with install scripts and a wheel. This is only used for new installs.
 
 ## General Prep
 
-Make a developer call-out for PRs to merge. Merge and test things out. Bump the version by editing `invokeai/version/invokeai_version.py`.

+While the release workflow does not include end-to-end tests, it does pause before publishing so you can download and test the final build.
 
 ## Release Workflow

+It is triggered on **tag push**, when the tag matches `v*`. It doesn't matter if you've prepped a release branch like `release/v3.5.0` or are releasing from `main` - it works the same.
+
+> Because commits are reference-counted, it is safe to create a release branch, tag it, let the workflow run, then delete the branch. So long as the tag exists, that commit will exist.
 
 ### Triggering the Workflow
 
-Ensure all commits that should be in the release are merged, and you have pulled them locally.
+Run `make tag-release` to tag the current commit and kick off the workflow.
 
-Double-check that you have checked out the commit that will represent the release (typically the latest commit on `main`).

-If this version's tag already exists for some reason (maybe you had to make a last minute change), the script will overwrite it.

-It's possible to test the python package before it gets published to PyPI. We've never had problems with it, so it's not necessary to do this.

-But, if you want to be extra-super careful, here's how to test it:
+- Download and unzip `dist.zip` and the installer from the **Summary** tab of the workflow
+- Run the installer script using the `--wheel` CLI arg, pointing at the wheel:
 
-- Download the `dist.zip` build artifact from the `build-wheel` job

-- Create a fresh Invoke install by following the [manual install guide](https://invoke-ai.github.io/InvokeAI/installation/manual/) - but instead of installing from PyPI, install from the wheel

 # FAQ
 
+!!! info "How to Reinstall"
+
+    Many issues can be resolved by re-installing the application. You won't lose any data by re-installing. We suggest downloading the [latest release](https://github.com/invoke-ai/InvokeAI/releases/latest) and using it to re-install the application. Consult the [installer guide](./installation/installer.md) for more information.
+
+    When you run the installer, you'll have an option to select the version to install. If you aren't ready to upgrade, you choose the current version to fix a broken install.

 ## Slow generation
 
 - Check the [system requirements] to ensure that your system is capable of generating images.
-- Follow the [Low-VRAM mode guide](./features/low-vram.md) to optimize performance.
-- Check that your generations are happening on your GPU (if you have one). Invoke will log what is being used for generation upon startup. If your GPU isn't used, re-install to and ensure you select the appropriate GPU option.
-- If you are on Windows with an Nvidia GPU, you may have exceeded your GPU's VRAM capacity and are triggering Nvidia's "sysmem fallback". There's a guide to opt out of this behaviour in the [Low-VRAM mode guide](./features/low-vram.md).
+- Check the `ram` setting in `invokeai.yaml`. This setting tells Invoke how much of your system RAM can be used to cache models. Having this too high or too low can slow things down. That said, it's generally safest to not set this at all and instead let Invoke manage it.
+- Check the `vram` setting in `invokeai.yaml`. This setting tells Invoke how much of your GPU VRAM can be used to cache models. Counter-intuitively, if this setting is too high, Invoke will need to do a lot of shuffling of models as it juggles the VRAM cache and the currently-loaded model. The default value of 0.25 is generally works well for GPUs without 16GB or more VRAM. Even on a 24GB card, the default works well.
+- Check that your generations are happening on your GPU (if you have one). InvokeAI will log what is being used for generation upon startup. If your GPU isn't used, re-install to ensure the correct versions of torch get installed.

+## Shared GPU Memory (Windows)
+
+!!! tip "Nvidia GPUs with driver 536.40"
+
+    This only applies to current Nvidia cards with driver 536.40 or later, released in June 2023.
+
+When the GPU doesn't have enough VRAM for a task, Windows is able to allocate some of its CPU RAM to the GPU. This is much slower than VRAM, but it does allow the system to generate when it otherwise might no have enough VRAM.
+
+When shared GPU memory is used, generation slows down dramatically - but at least it doesn't crash.
+
+If you'd like to opt out of this behavior and instead get an error when you exceed your GPU's VRAM, follow [this guide from Nvidia](https://nvidia.custhelp.com/app/answers/detail/a_id/5490).
+
+Here's how to get the python path required in the linked guide:
+
+- Run `invoke.bat`.
+- Select option 2 for developer console.
+- At least one python path will be printed. Copy the path that includes your invoke installation directory (typically the first).
+
+## Installer cannot find python (Windows)
+
+Ensure that you checked **Add python.exe to PATH** when installing Python. This can be found at the bottom of the Python Installer window. If you already have Python installed, you can re-run the python installer, choose the Modify option and check the box.

+   - If you run into an error with `typing_extensions`, re-open the developer console and run: `pip install -U typing-extensions`
+
+Note that v3.4.0 is an old, unsupported version. Please upgrade to the [latest release].
+
+## Install failed and says `pip` is out of date
+
+An out of date `pip` typically won't cause an installation to fail. The cause of the error can likely be found above the message that says `pip` is out of date.

+If you saw that warning but the install went well, don't worry about it (but you can update `pip` afterwards if you'd like).
 
 ## Replicate image found online
 
 Most example images with prompts that you'll find on the internet have been generated using different software, so you can't expect to get identical results. In order to reproduce an image, you need to replicate the exact settings and processing steps, including (but not limited to) the model, the positive and negative prompts, the seed, the sampler, the exact image size, any upscaling steps, etc.

+## Out of Memory Issues
+
+The models are large, VRAM is expensive, and you may find yourself
+faced with Out of Memory errors when generating images. Here are some
+tips to reduce the problem:
+
+!!! info "Optimizing for GPU VRAM"
+
+    === "4GB VRAM GPU"
+
+        This should be adequate for 512x512 pixel images using Stable Diffusion 1.5
+        and derived models, provided that you do not use the NSFW checker. It won't be loaded unless you go into the UI settings and turn it on.
+
+        If you are on a CUDA-enabled GPU, we will automatically use xformers or torch-sdp to reduce VRAM requirements, though you can explicitly configure this. See the [configuration docs].
+
+    === "6GB VRAM GPU"
+
+        This is a border case. Using the SD 1.5 series you should be able to
+        generate images up to 640x640 with the NSFW checker enabled, and up to
+        1024x1024 with it disabled.
+
+        If you run into persistent memory issues there are a series of
+        environment variables that you can set before launching InvokeAI that
+        alter how the PyTorch machine learning library manages memory. See
+        <https://pytorch.org/docs/stable/notes/cuda.html#memory-management> for
+        a list of these tweaks.
+
+    === "12GB VRAM GPU"
+
+        This should be sufficient to generate larger images up to about 1280x1280.
+  
+## Checkpoint Models Load Slowly or Use Too Much RAM
+
+The difference between diffusers models (a folder containing multiple
+subfolders) and checkpoint models (a file ending with .safetensors or
+.ckpt) is that InvokeAI is able to load diffusers models into memory
+incrementally, while checkpoint models must be loaded all at
+once. With very large models, or systems with limited RAM, you may
+experience slowdowns and other memory-related issues when loading
+checkpoint models.
+
+To solve this, go to the Model Manager tab (the cube), select the
+checkpoint model that's giving you trouble, and press the "Convert"
+button in the upper right of your browser window. This will convert the
+checkpoint into a diffusers model, after which loading should be
+faster and less memory-intensive.

-title: Low-VRAM mode
----
-
-As of v5.6.0, Invoke has a low-VRAM mode. It works on systems with dedicated GPUs (Nvidia GPUs on Windows/Linux and AMD GPUs on Linux).
-
-This allows you to generate even if your GPU doesn't have enough VRAM to hold full models. Most users should be able to run even the beefiest models - like the ~24GB unquantised FLUX dev model.
-
-## Enabling Low-VRAM mode
-
-To enable Low-VRAM mode, add this line to your `invokeai.yaml` configuration file, then restart Invoke:
-
-```yaml
-enable_partial_loading: true
-```
-
-**Windows users should also [disable the Nvidia sysmem fallback](#disabling-nvidia-sysmem-fallback-windows-only)**.
-
-It is possible to fine-tune the settings for best performance or if you still get out-of-memory errors (OOMs).
-
-!!! tip "How to find `invokeai.yaml`"
-
-    The `invokeai.yaml` configuration file lives in your install directory. To access it, run the **Invoke Community Edition** launcher and click the install location. This will open your install directory in a file explorer window.
-
-    You'll see `invokeai.yaml` there and can edit it with any text editor. After making changes, restart Invoke.
-
-    If you don't see `invokeai.yaml`, launch Invoke once. It will create the file on its first startup.
-
-## Details and fine-tuning
-
-Low-VRAM mode involves 4 features, each of which can be configured or fine-tuned:
-
-- Partial model loading (`enable_partial_loading`)
-- PyTorch CUDA allocator config (`pytorch_cuda_alloc_conf`)
-- Dynamic RAM and VRAM cache sizes (`max_cache_ram_gb`, `max_cache_vram_gb`)
-- Working memory (`device_working_mem_gb`)
-- Keeping a RAM weight copy (`keep_ram_copy_of_weights`)
-
-Read on to learn about these features and understand how to fine-tune them for your system and use-cases.
-
-### Partial model loading
-
-Invoke's partial model loading works by streaming model "layers" between RAM and VRAM as they are needed.
-
-When an operation needs layers that are not in VRAM, but there isn't enough room to load them, inactive layers are offloaded to RAM to make room.
-
-#### Enabling partial model loading
-
-As described above, you can enable partial model loading by adding this line to `invokeai.yaml`:
-
-```yaml
-enable_partial_loading: true
-```
-
-### PyTorch CUDA allocator config
-
-The PyTorch CUDA allocator's behavior can be configured using the `pytorch_cuda_alloc_conf` config. Tuning the allocator configuration can help to reduce the peak reserved VRAM. The optimal configuration is dependent on many factors (e.g. device type, VRAM, CUDA driver version, etc.), but switching from PyTorch's native allocator to using CUDA's built-in allocator works well on many systems. To try this, add the following line to your `invokeai.yaml` file:
-
-```yaml
-pytorch_cuda_alloc_conf: "backend:cudaMallocAsync"
-```
-
-A more complete explanation of the available configuration options is [here](https://pytorch.org/docs/stable/notes/cuda.html#optimizing-memory-usage-with-pytorch-cuda-alloc-conf).
-
-### Dynamic RAM and VRAM cache sizes
-
-Loading models from disk is slow and can be a major bottleneck for performance. Invoke uses two model caches - RAM and VRAM - to reduce loading from disk to a minimum.
-
-By default, Invoke manages these caches' sizes dynamically for best performance.
-
-#### Fine-tuning cache sizes
-
-Prior to v5.6.0, the cache sizes were static, and for best performance, many users needed to manually fine-tune the `ram` and `vram` settings in `invokeai.yaml`.
-
-As of v5.6.0, the caches are dynamically sized. The `ram` and `vram` settings are no longer used, and new settings are added to configure the cache.
-
-**Most users will not need to fine-tune the cache sizes.**
-
-But, if your GPU has enough VRAM to hold models fully, you might get a perf boost by manually setting the cache sizes in `invokeai.yaml`:
-
-```yaml
-# The default max cache RAM size is logged on InvokeAI startup. It is determined based on your system RAM / VRAM.
-# You can override the default value by setting `max_cache_ram_gb`.
-# Increasing `max_cache_ram_gb` will increase the amount of RAM used to cache inactive models, resulting in faster model
-# reloads for the cached models.
-# As an example, if your system has 32GB of RAM and no other heavy processes, setting the `max_cache_ram_gb` to 28GB
-# might be a good value to achieve aggressive model caching.
-max_cache_ram_gb: 28
-
-# The default max cache VRAM size is adjusted dynamically based on the amount of available VRAM (taking into
-# consideration the VRAM used by other processes).
-# You can override the default value by setting `max_cache_vram_gb`.
-# CAUTION: Most users should not manually set this value. See warning below.
-max_cache_vram_gb: 16
-```
-
-!!! warning "Max safe value for `max_cache_vram_gb`"
-
-    Most users should not manually configure the `max_cache_vram_gb`. This configuration value takes precedence over the `device_working_mem_gb` and any operations that explicitly reserve additional working memory (e.g. VAE decode). As such, manually configuring it increases the likelihood of encountering out-of-memory errors.
-
-    For users who wish to configure `max_cache_vram_gb`, the max safe value can be determined by subtracting `device_working_mem_gb` from your GPU's VRAM. As described below, the default for `device_working_mem_gb` is 3GB.
-
-    For example, if you have a 12GB GPU, the max safe value for `max_cache_vram_gb` is `12GB - 3GB = 9GB`.
-
-    If you had increased `device_working_mem_gb` to 4GB, then the max safe value for `max_cache_vram_gb` is `12GB - 4GB = 8GB`.
-
-    Most users who override `max_cache_vram_gb` are doing so because they wish to use significantly less VRAM, and should be setting `max_cache_vram_gb` to a value significantly less than the 'max safe value'.
-
-### Working memory
-
-Invoke cannot use _all_ of your VRAM for model caching and loading. It requires some VRAM to use as working memory for various operations.
-
-Invoke reserves 3GB VRAM as working memory by default, which is enough for most use-cases. However, it is possible to fine-tune this setting if you still get OOMs.
-
-#### Fine-tuning working memory
-
-You can increase the working memory size in `invokeai.yaml` to prevent OOMs:
-
-```yaml
-# The default is 3GB - bump it up to 4GB to prevent OOMs.
-device_working_mem_gb: 4
-```
-
-!!! tip "Operations may request more working memory"
-
-    For some operations, we can determine VRAM requirements in advance and allocate additional working memory to prevent OOMs.
-
-    VAE decoding is one such operation. This operation converts the generation process's output into an image. For large image outputs, this might use more than the default working memory size of 3GB.
-
-    During this decoding step, Invoke calculates how much VRAM will be required to decode and requests that much VRAM from the model manager. If the amount exceeds the working memory size, the model manager will offload cached model layers from VRAM until there's enough VRAM to decode.
-
-    Once decoding completes, the model manager "reclaims" the extra VRAM allocated as working memory for future model loading operations.
-
-### Keeping a RAM weight copy
-
-Invoke has the option of keeping a RAM copy of all model weights, even when they are loaded onto the GPU. This optimization is _on_ by default, and enables faster model switching and LoRA patching. Disabling this feature will reduce the average RAM load while running Invoke (peak RAM likely won't change), at the cost of slower model switching and LoRA patching. If you have limited RAM, you can disable this optimization:
-
-```yaml
-# Set to false to reduce the average RAM usage at the cost of slower model switching and LoRA patching.
-keep_ram_copy_of_weights: false
-```
-
-### Disabling Nvidia sysmem fallback (Windows only)
-
-On Windows, Nvidia GPUs are able to use system RAM when their VRAM fills up via **sysmem fallback**. While it sounds like a good idea on the surface, in practice it causes massive slowdowns during generation.
-
-It is strongly suggested to disable this feature:
-
-- Open the **NVIDIA Control Panel** app.
-- Expand **3D Settings** on the left panel.
-- Click **Manage 3D Settings** in the left panel.
-- Find **CUDA - Sysmem Fallback Policy** in the right panel and set it to **Prefer No Sysmem Fallback**.
-
-![cuda-sysmem-fallback](./cuda-sysmem-fallback.png)
-
-!!! tip "Invoke does the same thing, but better"
-
-    If the sysmem fallback feature sounds familiar, that's because Invoke's partial model loading strategy is conceptually very similar - use VRAM when there's room, else fall back to RAM.
-
-    Unfortunately, the Nvidia implementation is not optimized for applications like Invoke and does more harm than good.
-
-## Troubleshooting
-
-### Windows page file
-
-Invoke has high virtual memory (a.k.a. 'committed memory') requirements. This can cause issues on Windows if the page file size limits are hit. (See this issue for the technical details on why this happens: https://github.com/invoke-ai/InvokeAI/issues/7563).
-
-If you run out of page file space, InvokeAI may crash. Often, these crashes will happen with one of the following errors:
-
-- InvokeAI exits with Windows error code `3221225477`
-- InvokeAI crashes without an error, but `eventvwr.msc` reveals an error with code `0xc0000005` (the hex equivalent of `3221225477`)
-
-If you are running out of page file space, try the following solutions:
-
-- Make sure that you have sufficient disk space for the page file to grow. Watch your disk usage as Invoke runs. If it climbs near 100% leading up to the crash, then this is very likely the source of the issue. Clear out some disk space to resolve the issue.
-- Make sure that your page file is set to "System managed size" (this is the default) rather than a custom size. Under the "System managed size" policy, the page file will grow dynamically as needed.

+# Automatic Install & Updates
+
+!!! tip "Use the installer to update"
+
+    Using the installer for updates will not erase any of your data (images, models, boards, etc). It only updates the core libraries used to run Invoke.
+
+    Simply use the same path you installed to originally to update your existing installation.
+
+Both release and pre-release versions can be installed using the installer. It also supports install through a wheel if needed.
+
+Be sure to review the [installation requirements] and ensure your system has everything it needs to install Invoke.
+
+## Getting the Latest Installer
+
+Download the `InvokeAI-installer-vX.Y.Z.zip` file from the [latest release] page. It is at the bottom of the page, under **Assets**.
+
+After unzipping the installer, you should have a `InvokeAI-Installer` folder with some files inside, including `install.bat` and `install.sh`.
+
+## Running the Installer
+
+!!! tip
+
+    Windows users should first double-click the `WinLongPathsEnabled.reg` file to prevent a failed installation due to long file paths.
+
+Double-click the install script:
+
+=== "Windows"
+
+    ```sh
+    install.bat
+    ```
+
+=== "Linux/macOS"
+
+    ```sh

+!!! warning "Untrusted Publisher (Windows)"
+
+    You may get a popup saying the file comes from an `Untrusted Publisher`. Click `More Info` and `Run Anyway` to get past this.
+
+The installation process is simple, with a few prompts:
+
+- Select the version to install. Unless you have a specific reason to install a specific version, select the default (the latest version).
+- Select location for the install. Be sure you have enough space in this folder for the base application, as described in the [installation requirements].
+- Select a GPU device.
+
+!!! info "Slow Installation"
+
+    The installer needs to download several GB of data and install it all. It may appear to get stuck at 99.9% when installing `pytorch` or during a step labeled "Installing collected packages".
+
+    If it is stuck for over 10 minutes, something has probably gone wrong and you should close the window and restart.
+
+## Running the Application
+
+Find the install location you selected earlier. Double-click the launcher script to run the app:
+
+=== "Windows"
+
+    ```sh
+    invoke.bat
+    ```
+
+=== "Linux/macOS"
+
+    ```sh
+    invoke.sh
+    ```
+
+Choose the first option to run the UI. After a series of startup messages, you'll see something like this:

+Updating is exactly the same as installing - download the latest installer, choose the latest version, enter your existing installation path, and the app will update. None of your data (images, models, boards, etc) will be erased.
+
+!!! info "Dependency Resolution Issues"
+
+    We've found that pip's dependency resolution can cause issues when upgrading packages. One very common problem was pip "downgrading" torch from CUDA to CPU, but things broke in other novel ways.
+
+    The installer doesn't have this kind of problem, so we use it for updating as well.

 ## Walkthrough
 
-We'll use [`uv`](https://github.com/astral-sh/uv) to install python and create a virtual environment, then install the `invokeai` package. `uv` is a modern, very fast alternative to `pip`.
-
-The following commands vary depending on the version of Invoke being installed and the system onto which it is being installed.
-
-1. Install `uv` as described in its [docs](https://docs.astral.sh/uv/getting-started/installation/#standalone-installer). We suggest using the standalone installer method.
-
-    Run `uv --version` to confirm that `uv` is installed and working. After installation, you may need to restart your terminal to get access to `uv`.
-
-2. Create a directory for your installation, typically in your home directory (e.g. `~/invokeai` or `$Home/invokeai`):
+1. Create a directory to contain your InvokeAI library, configuration files, and models. This is known as the "runtime" or "root" directory, and typically lives in your home directory under the name `invokeai`.
 
     === "Linux/macOS"
 
         ```bash
         mkdir ~/invokeai
-        cd ~/invokeai

     === "Windows (PowerShell)"
 
         ```bash
         mkdir $Home/invokeai
-        cd $Home/invokeai
         ```
 
-3. Create a virtual environment in that directory:
+1. Enter the root directory and create a virtual Python environment within it named `.venv`.
 
-    ```sh
-    uv venv --relocatable --prompt invoke --python 3.12 --python-preference only-managed .venv
-    ```
+    !!! warning "Virtual Environment Location"
 
-    This command creates a portable virtual environment at `.venv` complete with a portable python 3.12. It doesn't matter if your system has no python installed, or has a different version - `uv` will handle everything.
+        While you may create the virtual environment anywhere in the file system, we recommend that you create it within the root directory as shown here. This allows the application to automatically detect its data directories.
 
-4. Activate the virtual environment:
+        If you choose a different location for the venv, then you _must_ set the `INVOKEAI_ROOT` environment variable or specify the root directory using the `--root` CLI arg.
+

     ```
 
-    If you determined you needed to use a torch backend in the previous step, you'll need to set the backend like this:
+1. Install the InvokeAI Package. The base command is `pip install InvokeAI --use-pep517`, but you may need to change this depending on your system and the desired features.

-    uv pip install <PACKAGE_SPECIFIER>==<VERSION> --python 3.12 --python-preference only-managed --torch-backend=<VERSION> --force-reinstall
-    ```
+    - You may need to provide an [extra index URL](https://pip.pypa.io/en/stable/cli/pip_install/#cmdoption-extra-index-url). Select your platform configuration using [this tool on the PyTorch website](https://pytorch.org/get-started/locally/).

-# Invoke Community Edition Quick Start
-
-Welcome to Invoke! Follow these steps to install, update, and get started creating.
-
-## Step 1: System Requirements
-
-Invoke runs on Windows 10+, macOS 14+ and Linux (Ubuntu 20.04+ is well-tested).
-
-Hardware requirements vary significantly depending on model and image output size. The requirements below are rough guidelines.
-
-- All Apple Silicon (M1, M2, etc) Macs work, but 16GB+ memory is recommended.
-- AMD GPUs are supported on Linux only. The VRAM requirements are the same as Nvidia GPUs.
-
-!!! info "Hardware Requirements (Windows/Linux)"

-        - Memory: At least 32GB RAM.
-        - Disk: 10GB for base installation plus 200GB for models.
-
-More detail on system requirements can be found [here](./requirements.md).
-
-## Step 2: Download and Set Up the Launcher
-
-The Launcher manages your Invoke install. Follow these instructions to download and set up the Launcher.
-
-!!! info "Instructions for each OS"
-
-    === "Windows"
-
-        - [Download for Windows](https://github.com/invoke-ai/launcher/releases/latest/download/Invoke.Community.Edition.Setup.latest.exe)
-        - Run the `EXE` to install the Launcher and start it.
-        - A desktop shortcut will be created; use this to run the Launcher in the future.
-        - You can delete the `EXE` file you downloaded.
-
-    === "macOS"
-
-        - [Download for macOS](https://github.com/invoke-ai/launcher/releases/latest/download/Invoke.Community.Edition-latest-arm64.dmg)
-        - Open the `DMG` and drag the app into `Applications`.
-        - Run the Launcher using its entry in `Applications`.
-        - You can delete the `DMG` file you downloaded.
-
-    === "Linux"
-
-        - [Download for Linux](https://github.com/invoke-ai/launcher/releases/latest/download/Invoke.Community.Edition-latest.AppImage)
-        - You may need to edit the `AppImage` file properties and make it executable.
-        - Optionally move the file to a location that does not require admin privileges and add a desktop shortcut for it.
-        - Run the Launcher by double-clicking the `AppImage` or the shortcut you made.
-
-## Step 3: Install Invoke
-
-Run the Launcher you just set up if you haven't already. Click **Install** and follow the instructions to install (or update) Invoke.
-
-If you have an existing Invoke installation, you can select it and let the launcher manage the install. You'll be able to update or launch the installation.
-
-!!! tip "Updating"
-
-    The Launcher will check for updates for itself _and_ Invoke.
-
-    - When the Launcher detects an update is available for itself, you'll get a small popup window. Click through this and the Launcher will update itself.
-    - When the Launcher detects an update for Invoke, you'll see a small green alert in the Launcher. Click that and follow the instructions to update Invoke.
-
-## Step 4: Launch
-
-Once installed, click **Finish**, then **Launch** to start Invoke.
-
-The very first run after an installation or update will take a few extra moments to get ready.
-
-!!! tip "Server Mode"
-
-    The launcher runs Invoke as a desktop application. You can enable **Server Mode** in the launcher's settings to disable this and instead access the UI through your web browser.
-
-## Step 5: Install Models
-
-With Invoke started up, you'll need to install some models.
-
-The quickest way to get started is to install a **Starter Model** bundle. If you already have a model collection, Invoke can use it.
-
-!!! info "Install Models"
-
-    === "Install a Starter Model bundle"
-
-        1. Go to the **Models** tab.
-        2. Click **Starter Models** on the right.
-        3. Click one of the bundles to install its models. Refer to the [system requirements](#step-1-confirm-system-requirements) if you're unsure which model architecture will work for your system.
-
-    === "Use my model collection"
-
-        4. Go to the **Models** tab.
-        5. Click **Scan Folder** on the right.
-        6. Paste the path to your models collection and click **Scan Folder**.
-        7. With **In-place install** enabled, Invoke will leave the model files where they are. If you disable this, **Invoke will move the models into its own folders**.
-
-You’re now ready to start creating!
-
-## Step 6: Learn the Basics
-
-We recommend watching our [Getting Started Playlist](https://www.youtube.com/playlist?list=PLvWK1Kc8iXGrQy8r9TYg6QdUuJ5MMx-ZO). It covers essential features and workflows, including:
-
-- Generating your first image.
-- Using control layers and reference guides.
-- Refining images with advanced workflows.
-
-## Troubleshooting
-
-If installation fails, retrying the install in Repair Mode may fix it. There's a checkbox to enable this on the Review step of the install flow.
-
-If that doesn't fix it, [clearing the `uv` cache](https://docs.astral.sh/uv/reference/cli/#uv-cache-clean) might do the trick:
-
-- Open and start the dev console (button at the bottom-left of the launcher).
-- Run `uv cache clean`.
-- Retry the installation. Enable Repair Mode for good measure.
-
-If you are still unable to install, try installing to a different location and see if that works.
-
-If you still have problems, ask for help on the Invoke [discord](https://discord.gg/ZmtBAhwWhy).
-
-## Other Installation Methods
-
-- You can install the Invoke application as a python package. See our [manual install](./manual.md) docs.
-- You can run Invoke with docker. See our [docker install](./docker.md) docs.

+InvokeAI
+
+Project homepage: https://github.com/invoke-ai/InvokeAI
+
+Preparations:
+
+  You will need to install Python 3.10 or higher for this installer
+  to work. Instructions are given here:
+  https://invoke-ai.github.io/InvokeAI/installation/INSTALL_AUTOMATED/
+
+  Before you start the installer, please open up your system's command
+  line window (Terminal or Command) and type the commands:
+
+     python --version
+
+  If all is well, it will print "Python 3.X.X", where the version number
+  is at least 3.10.*, and not higher than 3.11.*.
+
+  If this works, check the version of the Python package manager, pip:
+
+     pip --version
+
+  You should get a message that indicates that the pip package
+  installer was derived from Python 3.10 or 3.11. For example:
+  "pip 22.0.1 from /usr/bin/pip (python 3.10)"
+
+Long Paths on Windows:
+
+  If you are on Windows, you will need to enable Windows Long Paths to
+  run InvokeAI successfully. If you're not sure what this is, you
+  almost certainly need to do this.
+
+  Simply double-click the "WinLongPathsEnabled.reg" file located in
+  this directory, and approve the Windows warnings. Note that you will
+  need to have admin privileges in order to do this.
+
+Launching the installer:
+
+  Windows: double-click the 'install.bat' file (while keeping it inside
+  the InvokeAI-Installer folder).
+
+  Linux and Mac: Please open the terminal application and run
+  './install.sh' (while keeping it inside the InvokeAI-Installer
+  folder).
+
+The installer will create a directory of your choice and install the
+InvokeAI application within it. This directory contains everything you need to run
+invokeai. Once InvokeAI is up and running, you may delete the
+InvokeAI-Installer folder at your convenience.
+
+For more information, please see
+https://invoke-ai.github.io/InvokeAI/installation/INSTALL_AUTOMATED/

     that adds a few extra parameters to support graph execution and the node editor UI.
 
-    If the field is a `ModelIdentifierField`, use the `ui_model_[base|type|variant|format]` args to filter the model list
-    in the Workflow Editor. Otherwise, use `ui_type` to provide extra type hints for the UI.

+      `Input.Direct` means a value must be provided on instantiation. \
+      `Input.Connection` means the value must be provided by a connection. \
+      `Input.Any` means either will do.
 
-    Don't use both `ui_type` and `ui_model_[base|type|variant|format]` - if both are provided, a warning will be
-    logged and `ui_type` will be ignored.
+    :param UIType ui_type: [None] Optionally provides an extra type hint for the UI. \
+      In some situations, the field's type is not enough to infer the correct UI type. \
+      For example, model selection fields should render a dropdown UI component to select a model. \
+      Internally, there is no difference between SD-1, SD-2 and SDXL model fields, they all use \
+      `MainModelField`. So to ensure the base-model-specific UI is rendered, you can use \
+      `UIType.SDXLMainModelField` to indicate that the field is an SDXL main model field.
 
-    Args:
-        input: The kind of input this field requires.
-        - `Input.Direct` means a value must be provided on instantiation.
-        - `Input.Connection` means the value must be provided by a connection.
-        - `Input.Any` means either will do.
+    :param UIComponent ui_component: [None] Optionally specifies a specific component to use in the UI. \
+      The UI will always render a suitable component, but sometimes you want something different than the default. \
+      For example, a `string` field will default to a single-line input, but you may want a multi-line textarea instead. \
+      For this case, you could provide `UIComponent.Textarea`.
 
-        ui_type: Optionally provides an extra type hint for the UI. In some situations, the field's type is not enough
-        to infer the correct UI type. For example, Scheduler fields are enums, but we want to render a special scheduler
-        dropdown in the UI. Use `UIType.Scheduler` to indicate this.
+    :param bool ui_hidden: [False] Specifies whether or not this field should be hidden in the UI.
 
-        ui_component: Optionally specifies a specific component to use in the UI. The UI will always render a suitable

-        ui_hidden: Specifies whether or not this field should be hidden in the UI.
-
-        ui_order: Specifies the order in which this field should be rendered in the UI. If omitted, the field will be
-        rendered after all fields with an explicit order, in the order they are defined in the Invocation class.
-
-        ui_model_base: Specifies the base model architectures to filter the model list by in the Workflow Editor. For
-        example, `ui_model_base=BaseModelType.StableDiffusionXL` will show only SDXL architecture models. This arg is
-        only valid if this Input field is annotated as a `ModelIdentifierField`.
-
-        ui_model_type: Specifies the model type(s) to filter the model list by in the Workflow Editor. For example,
-        `ui_model_type=ModelType.VAE` will show only VAE models. This arg is only valid if this Input field is
-        annotated as a `ModelIdentifierField`.
-
-        ui_model_variant: Specifies the model variant(s) to filter the model list by in the Workflow Editor. For example,
-        `ui_model_variant=ModelVariantType.Inpainting` will show only inpainting models. This arg is only valid if this
-        Input field is annotated as a `ModelIdentifierField`.
-
-        ui_model_format: Specifies the model format(s) to filter the model list by in the Workflow Editor. For example,
