+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+    9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-## Installation
 
 <details>
-  <summary>Installation (Linux and macOS)</summary>
+  <summary>Prerequisites - Drivers </summary>
+  
+#### Install your Windows hardware drivers
+* [AMD RDNA Users] Download the latest driver [here](https://www.amd.com/en/support/kb/release-notes/rn-rad-win-23-2-1).
+* [macOS Users] Download and install the 1.3.216 Vulkan SDK from [here](https://sdk.lunarg.com/sdk/download/1.3.216.0/mac/vulkansdk-macos-1.3.216.0.dmg). Newer versions of the SDK will not work. 
+* [Nvidia Users] Download and install the latest CUDA / Vulkan drivers from [here](https://developer.nvidia.com/cuda-downloads)
+  
+#### Linux Drivers
+* MESA / RADV drivers wont work with FP16. Please use the latest AMGPU-PRO drivers (non-pro OSS drivers also wont work) or the latest NVidia Linux Drivers.
+
+Other users please ensure you have your latest vendor drivers and Vulkan SDK from [here](https://vulkan.lunarg.com/sdk/home) and if you are using vulkan check `vulkaninfo` works in a terminal window
+
+</details>
+
+
+ 
+### Quick Start for SHARK Stable Diffusion for Windows 10/11 Users
+
+Install the Driver from [Prerequisites](https://github.com/nod-ai/SHARK#install-your-hardware-drivers) above 
+
+Download the [stable release](https://github.com/nod-ai/shark/releases/latest)
+
+Double click the .exe and you should have the [UI](http://localhost:8080/) in the browser. 
+
+If you have custom models put them in a `models/` directory where the .exe is. 
+
+Enjoy. 
+
+<details>
+  <summary>More installation notes</summary>
+* We recommend that you download EXE in a new folder, whenever you download a new EXE version. If you download it in the same folder as a previous install, you must delete the old `*.vmfb` files with `rm *.vmfb`. You can also use `--clear_all` flag once to clean all the old files. 
+* If you recently updated the driver or this binary (EXE file), we recommend you clear all the local artifacts with `--clear_all` 
+
+## Running
+
+* Open a Command Prompt or Powershell terminal, change folder (`cd`) to the .exe folder. Then run the EXE from the command prompt. That way, if an error occurs, you'll be able to cut-and-paste it to ask for help. (if it always works for you without error, you may simply double-click the EXE)
+* The first run may take few minutes when the models are downloaded and compiled. Your patience is appreciated. The download could be about 5GB.
+* You will likely see a Windows Defender message asking you to give permission to open a web server port. Accept it.
+* Open a browser to access the Stable Diffusion web server. By default, the port is 8080, so you can go to http://localhost:8080/.
+
+## Stopping
+
+* Select the command prompt that's running the EXE. Press CTRL-C and wait a moment or close the terminal.

+pytest tank/test_models.py -k "MiniLM"
+```
+  
+### How to use your locally built IREE / Torch-MLIR with SHARK
+If you are a *Torch-mlir developer or an IREE developer* and want to test local changes you can uninstall
+the provided packages with `pip uninstall torch-mlir` and / or `pip uninstall iree-compiler iree-runtime` and build locally
+with Python bindings and set your PYTHONPATH as mentioned [here](https://github.com/iree-org/iree/tree/main/docs/api_docs/python#install-iree-binaries)
+for IREE and [here](https://github.com/llvm/torch-mlir/blob/main/development.md#setup-python-environment-to-export-the-built-python-packages)
+for Torch-MLIR.
+
+How to use your locally built Torch-MLIR with SHARK:
+```shell
+1.) Run `./setup_venv.sh in SHARK` and activate `shark.venv` virtual env.
+2.) Run `pip uninstall torch-mlir`.
+3.) Go to your local Torch-MLIR directory.
+4.) Activate mlir_venv virtual envirnoment.
+5.) Run `pip uninstall -r requirements.txt`.
+6.) Run `pip install -r requirements.txt`.
+7.) Build Torch-MLIR.
+8.) Activate shark.venv virtual environment from the Torch-MLIR directory.
+8.) Run `export PYTHONPATH=`pwd`/build/tools/torch-mlir/python_packages/torch_mlir:`pwd`/examples` in the Torch-MLIR directory.
+9.) Go to the SHARK directory.
+```
+Now the SHARK will use your locally build Torch-MLIR repo.
+
+
+## Benchmarking Dispatches
+
+To produce benchmarks of individual dispatches, you can add `--dispatch_benchmarks=All --dispatch_benchmarks_dir=<output_dir>` to your pytest command line argument.  
+If you only want to compile specific dispatches, you can specify them with a space seperated string instead of `"All"`.  E.G. `--dispatch_benchmarks="0 1 2 10"`
+
+For example, to generate and run dispatch benchmarks for MiniLM on CUDA:
+```
+pytest -k "MiniLM and torch and static and cuda" --benchmark_dispatches=All -s --dispatch_benchmarks_dir=./my_dispatch_benchmarks                                                                                
+```
+The given command will populate `<dispatch_benchmarks_dir>/<model_name>/` with an `ordered_dispatches.txt` that lists and orders the dispatches and their latencies, as well as folders for each dispatch that contain .mlir, .vmfb, and results of the benchmark for that dispatch.
+
+if you want to instead incorporate this into a python script, you can pass the `dispatch_benchmarks` and `dispatch_benchmarks_dir` commands when initializing `SharkInference`, and the benchmarks will be generated when compiled.  E.G:
+
+```
+shark_module = SharkInference(
+        mlir_model,
+        func_name,
+        device=args.device,
+        mlir_dialect="tm_tensor",
+        dispatch_benchmarks="all",
+        dispatch_benchmarks_dir="results"
+    )
 ```
 
+Output will include:
+- An ordered list ordered-dispatches.txt of all the dispatches with their runtime
+- Inside the specified directory, there will be a directory for each dispatch (there will be mlir files for all dispatches, but only compiled binaries and benchmark data for the specified dispatches)
+- An .mlir file containing the dispatch benchmark 
+- A compiled .vmfb file containing the dispatch benchmark
+- An .mlir file containing just the hal executable
+- A compiled .vmfb file of the hal executable
+- A .txt file containing benchmark output

+Compile / Run Instructions:
+
+To compile .vmfb for SD (vae, unet, CLIP), run the following commands with the .mlir in your local shark_tank cache (default location for Linux users is `~/.local/shark_tank`). These will be available once the script from [this README](https://github.com/nod-ai/SHARK/blob/main/shark/examples/shark_inference/stable_diffusion/README.md) is run once.
+Running the script mentioned above with the `--save_vmfb` flag will also save the .vmfb in your SHARK base directory if you want to skip straight to benchmarks.
