## Live Preview
![live-512](https://user-images.githubusercontent.com/844287/192097249-729a0a1e-a677-485e-9ccc-16a9e848fabe.gif)


# System Requirements
1. Windows 10/11, or Linux. Experimental support for Mac is coming soon.
2. An NVIDIA graphics card, preferably with 4GB or more of VRAM. But if you don't have a compatible graphics card, you can still use it with a "Use CPU" setting. It'll be very slow, but it should still work.

You do not need anything else. You do not need WSL, Docker or Conda. The installer will take care of it.

# Installation
1. **Download** [for Windows](https://github.com/cmdr2/stable-diffusion-ui/releases/download/v2.16/stable-diffusion-ui-win64.zip) or [for Linux](https://github.com/cmdr2/stable-diffusion-ui/releases/download/v2.16/stable-diffusion-ui-linux.tar.xz).

2. **Extract**:
  - For Windows: After unzipping the file, please move the `stable-diffusion-ui` folder to your `C:` (or any drive like D:, at the top root level), e.g. `C:\stable-diffusion-ui`. This will avoid a common problem with Windows (file path length limits).
  - For Linux: After extracting the .tar.xz file, please open a terminal, and go to the `stable-diffusion-ui` directory.

3. **Run**:
  - For Windows: `Start Stable Diffusion UI.cmd` by double-clicking it.
  - For Linux: In the terminal, run `./start.sh` (or `bash start.sh`)

This will automatically install Stable Diffusion, set it up, and start the interface. No additional steps are needed.

**To Uninstall:** Just delete the `stable-diffusion-ui` folder to uninstall all the downloaded packages.


# Usage
Open http://localhost:9000 in your browser (after running step 3 previously). It may take a few moments for the back-end to be ready.

## With a text description
1. Enter a text prompt, like `a photograph of an astronaut riding a horse` in the textbox.
2. Press `Make Image`. This will take some time, depending on your system's processing power.
3. See the image generated using your prompt.

## With an image
1. Click `Browse..` next to `Initial Image`. Select your desired image.
2. An optional text prompt can help you further describe the kind of image you want to generate.
3. Press `Make Image`. See the image generated using your prompt.

You can use Face Correction or Upscaling to improve the image further.

**Pro tip:** You can also click `Use as Input` on a generated image, to use it as the input image for your next generation. This can be useful for sequentially refining the generated image with a single click.

**Another tip:** Images with the same aspect ratio of your generated image work best. E.g. 1:1 if you're generating images sized 512x512.

## Problems? Troubleshooting
Please try the common [troubleshooting](Troubleshooting.md) steps. If that doesn't fix it, please ask on the [discord server](https://discord.com/invite/u9yhsFmEkB), or [file an issue](https://github.com/cmdr2/stable-diffusion-ui/issues).

# Image Settings
You can also set the configuration like `seed`, `width`, `height`, `num_outputs`, `num_inference_steps` and `guidance_scale` using the 'show' button next to 'Image settings'.

Use the same `seed` number to get the same image for a certain prompt. This is useful for refining a prompt without losing the basic image design. Enable the `random images` checkbox to get random images.

saved be automically, or to tune the Stable Diffusion image generation.
