 |  [Installation and Updates][installation docs] - [Documentation and Tutorials][docs home] - [Bug Reports][github issues] - [Contributing][contributing docs]  | 
 
-</div>
+# Installation
 
-## Quick Start
+To get started with Invoke, [Download the Installer](https://www.invoke.com/downloads).
 
-1. Download and unzip the installer from the bottom of the [latest release][latest release link].
-2. Run the installer script.
+For detailed step by step instructions, or for instructions on manual/docker installations, visit our documentation on [Installation and Updates][installation docs]
 
-   - **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 app is published in twice, in different build formats.
+The Invoke application is published as a python package on [PyPI]. This includes both a source distribution and built distribution (a wheel).
 
-- 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.
+Most users install it with the [Launcher](https://github.com/invoke-ai/launcher/), others with `pip`.
+
+The launcher uses GitHub as the source of truth for available releases.
+
+## 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.
 
 ## General Prep
 
-Make a developer call-out for PRs to merge. Merge and test things out.
-
-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.
+Make a developer call-out for PRs to merge. Merge and test things out. Bump the version by editing `invokeai/version/invokeai_version.py`.
 
 ## Release Workflow
 
 The `release.yml` workflow runs a number of jobs to handle code checks, tests, build and publish on PyPI.
 
-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.
+It is triggered on **tag push**, when the tag matches `v*`.
 
 ### Triggering the Workflow
 
-Run `make tag-release` to tag the current commit and kick off the workflow.
+Ensure all commits that should be in the release are merged, and you have pulled them locally.
 
-The release may also be dispatched [manually].
+Double-check that you have checked out the commit that will represent the release (typically the latest commit on `main`).
+
+Run `make tag-release` to tag the current commit and kick off the workflow. You will be prompted to provide a message - use the version specifier.
+
+If this version's tag already exists for some reason (maybe you had to make a last minute change), the script will overwrite it.
+
+> In case you cannot use the Make target, the release may also be dispatched [manually] via GH.
 
 ### Workflow Jobs and Process
 
-The workflow consists of a number of concurrently-run jobs, and two final publish jobs.

 #### Check and Test Jobs
 
+Next, these jobs run and must pass. They are the same jobs that are run for every PR.

 - **`python-checks`**: runs `ruff` (format and lint)

+At this point, the release workflow pauses as the remaining publish jobs require approval.
 
-Because the installer pulls from PyPI, and we haven't published to PyPI yet, you will need to install from the wheel:
+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.
 
-- 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:
+But, if you want to be extra-super careful, here's how to test it:
 
-  ```sh
-  ./install.sh --wheel ../InvokeAI-4.0.0rc6-py3-none-any.whl
-  ```
-
-- Install to a temporary directory so you get the new user experience
-- Download a model and generate
-
-> The same wheel file is bundled in the installer and in the `dist` artifact, which is uploaded to PyPI. You should end up with the exactly the same installation as if the installer got the wheel from PyPI.
+- Download the `dist.zip` build artifact from the `build-wheel` job
+- Unzip it and find the wheel file
+- 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
+- Test the app

 #### `publish-pypi` Job
 
 Publishes the distribution on the production PyPI index, using the `pypi` GitHub environment.
 
-## Publish the GitHub Release with installer
+It's a good idea to wait to approve and run this job until you have the release notes ready!
 
-Once the release is published to PyPI, it's time to publish the GitHub release.
+## Prep and publish the GitHub Release
 
 1. [Draft a new release] on GitHub, choosing the tag that triggered the release.
-1. Write the release notes, describing important changes. The **Generate release notes** button automatically inserts the changelog and new contributors, and you can copy/paste the intro from previous releases.
-1. Use `scripts/get_external_contributions.py` to get a list of external contributions to shout out in the release notes.
-1. Upload the zip file created in **`build`** job into the Assets section of the release notes.
-1. Check **Set as a pre-release** if it's a pre-release.
-1. Check **Create a discussion for this release**.
-1. Publish the release.
-1. Announce the release in Discord.
-
-> **TODO** Workflows can create a GitHub release from a template and upload release assets. One popular action to handle this is [ncipollo/release-action]. A future enhancement to the release process could set this up.
-
-## Manual Build
-
-The `build installer` workflow can be dispatched manually. This is useful to test the installer for a given branch or tag.
-
-No checks are run, it just builds.
+2. The **Generate release notes** button automatically inserts the changelog and new contributors. Make sure to select the correct tags for this release and the last stable release. GH often selects the wrong tags - do this manually.
+3. Write the release notes, describing important changes. Contributions from community members should be shouted out. Use the GH-generated changelog to see all contributors. If there are Weblate translation updates, open that PR and shout out every person who contributed a translation.
+4. Check **Set as a pre-release** if it's a pre-release.
+5. Approve and wait for the `publish-pypi` job to finish if you haven't already.
+6. Publish the GH release.
+7. Post the release in Discord in the [releases](https://discord.com/channels/1020123559063990373/1149260708098359327) channel with abbreviated notes. For example:
+   > Invoke v5.7.0 (stable): <https://github.com/invoke-ai/InvokeAI/releases/tag/v5.7.0>
+   >
+   > It's a pretty big one - Form Builder, Metadata Nodes (thanks @SkunkWorxDark!), and much more.
+8. Right click the message in releases and copy the link to it. Then, post that link in the [new-release-discussion](https://discord.com/channels/1020123559063990373/1149506274971631688) channel. For example:

+4. Create an directory for user data (images, models, db, etc). This is typically at `~/invokeai`, but if you already have a non-dev install, you may want to create a separate directory for the dev install.
 
-6. Install the repo as an [editable install][editable install link]:
+5. Follow the [manual install][manual install link] guide, with some modifications to the install command:
+
+      - Use `.` instead of `invokeai` to install from the current directory. You don't need to specify the version.
+
+      - Add `-e` after the `install` operation to make this an [editable install][editable install link]. That means your changes to the python code will be reflected when you restart the Invoke server.
+
+      - When installing the `invokeai` package, add the `dev`, `test` and `docs` package options to the package specifier. You may or may not need the `xformers` option - follow the manual install guide to figure that out. So, your package specifier will be either `".[dev,test,docs]"` or `".[dev,test,docs,xformers]"`. Note the quotes!
+
+     With the modifications made, the install command should look something like this:
 
       ```sh
-      pip install -e ".[dev,test,xformers]" --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu121
+      uv pip install -e ".[dev,test,docs,xformers]" --python 3.12 --python-preference only-managed --index=https://download.pytorch.org/whl/cu126 --reinstall
       ```
 
-      Refer to the [manual installation][manual install link]] instructions for more determining the correct install options. `xformers` is optional, but `dev` and `test` are not.
+6. At this point, you should have Invoke installed, a venv set up and activated, and the server running. But you will see a warning in the terminal that no UI was found. If you go to the URL for the server, you won't get a UI.
+
+      This is because the UI build is not distributed with the source code. You need to build it manually. End the running server instance.
+
+      If you only want to edit the docs, you can stop here and skip to the **Documentation** section below.
 
 7. Install the frontend dev toolchain:
 
-   - [`nodejs`](https://nodejs.org/) (recommend v20 LTS)
-   - [`pnpm`](https://pnpm.io/8.x/installation) (must be v8 - not v9!)
+      - [`nodejs`](https://nodejs.org/) (v20+)
+
+      - [`pnpm`](https://pnpm.io/8.x/installation) (must be v8 - not v9!)
 
 8. Do a production build of the frontend:
 
       ```sh
-      cd PATH_TO_INVOKEAI_REPO/invokeai/frontend/web
+      cd <PATH_TO_INVOKEAI_REPO>/invokeai/frontend/web
       pnpm i
       pnpm build
       ```
 
-9. Start the application:
-
-      ```sh
-      cd PATH_TO_INVOKEAI_REPO
-      python scripts/invokeai-web.py
-      ```
-
-10. Access the UI at `localhost:9090`.
+9. Restart the server and navigate to the URL. You should get a UI. After making changes to the python code, restart the server to see those changes.
 
 ## Updating the UI

 ## Slow generation
 
 - Check the [system requirements] to ensure that your system is capable of generating images.
-- 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.
-- If you are on Windows, you may have exceeded your GPU's VRAM capacity and are using slower [shared GPU memory](#shared-gpu-memory-windows). There's a guide to opt out of this behaviour in the linked FAQ entry.

+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.

-
-## Automated Installer & Updates
-
-✅ The automated [installer](./installer.md) is the best way to install Invoke.
-
-⬆️ The same installer is also the best way to update Invoke - simply rerun it for the same folder you installed to.
-
-The installation process simply manages installation for the core libraries & application dependencies that run Invoke.
-
-Models, images, or other assets in the Invoke root folder won't be affected by the installation process.
-
-## Manual Install
-
-If you are familiar with python and want more control over the packages that are installed, you can [install Invoke manually via PyPI](./manual.md).
-
-Updates are managed by reinstalling the latest version through PyPi.
-
-## Developer Install
-
-If you want to contribute to InvokeAI, you'll need to set up a [dev environment](../contributing/dev-environment.md).
-
-## Docker

-# 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
-    install.sh
-    ```
-
-!!! info "Running the Installer from the commandline"
-
-    You can also run the install script from cmd/powershell (Windows) or terminal (Linux/macOS).
-
-!!! 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:
-
-```sh
-Uvicorn running on http://127.0.0.1:9090 (Press CTRL+C to quit)
-```
-
-Copy the URL into your browser and you should see the UI.
-
-## Improved Outpainting with PatchMatch
-
-PatchMatch is an extra add-on that can improve outpainting. Windows users are in luck - it works out of the box.
-
-On macOS and Linux, a few extra steps are needed to set it up. See the [PatchMatch installation guide](./patchmatch.md).
-
-## First-time Setup
-
-You will need to [install some models] before you can generate.
-
-Check the [configuration docs] for details on configuring the application.
-
-## Updating
-
-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
 
-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`.
+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`):
 
     === "Linux/macOS"
 
         ```bash
         mkdir ~/invokeai

-
-1. Enter the root directory and create a virtual Python environment within it named `.venv`.
-
-    !!! warning "Virtual Environment Location"
-
-        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.
-
-        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.
-
-    === "Linux/macOS"
-
-        ```bash
-        cd ~/invokeai

+    If you determined you needed to use a `PyPI` index URL in the previous step, you'll need to add `--index=<INDEX_URL>` like this:
 
-    - 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/). Copy the `--extra-index-url` string from this and append it to your install command.

+
+## 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)"
+
+    === "SD1.5 - 512×512"
+
+        - GPU: Nvidia 10xx series or later, 4GB+ VRAM.
+        - Memory: At least 8GB RAM.
+        - Disk: 10GB for base installation plus 30GB for models.
+
+    === "SDXL - 1024×1024"
+
+        - GPU: Nvidia 20xx series or later, 8GB+ VRAM.
+        - Memory: At least 16GB RAM.
+        - Disk: 10GB for base installation plus 100GB for models.
+
+    === "FLUX - 1024×1024"
+
+        - GPU: Nvidia 20xx series or later, 10GB+ VRAM.
+        - 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
+
+Download the most launcher for your operating system:
+
+- [Download for Windows](https://download.invoke.ai/Invoke%20Community%20Edition.exe)
+- [Download for macOS](https://download.invoke.ai/Invoke%20Community%20Edition.dmg)
+- [Download for Linux](https://download.invoke.ai/Invoke%20Community%20Edition.AppImage)
+
+## Step 3: Install or Update
+
+Run the launcher you just downloaded, click **Install** and follow the instructions to get set up.
+
+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.
+
+!!! warning "Problem running the launcher on macOS"
+
+    macOS may not allow you to run the launcher. We are working to resolve this by signing the launcher executable. Until that is done, you can manually flag the launcher as safe:
+
+    - Open the **Invoke Community Edition.dmg** file.
+    - Drag the launcher to **Applications**.
+    - Open a terminal.
+    - Run `xattr -d 'com.apple.quarantine' /Applications/Invoke\ Community\ Edition.app`.
+
+    You should now be able to run the launcher.
+
+## 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
