# Step 1: Download and extract the installer
Click the download button for your operating system:

</p>

## On Windows:
1. Unzip/extract the folder `stable-diffusion-ui` which should be in your downloads folder, unless you changed your default downloads destination.
2. Move the `stable-diffusion-ui` folder to your `C:` drive (or any other drive like `D:`, at the top root level). `C:\stable-diffusion-ui` or `D:\stable-diffusion-ui` as examples. This will avoid a common problem with Windows (file path length limits).
## On Linux:
1. Unzip/extract the folder `stable-diffusion-ui` which should be in your downloads folder, unless you changed your default downloads destination.
2. Open a terminal window, and navigate to the `stable-diffusion-ui` directory.

# Step 2: Run the program
## On Windows: 
Double-click `Start Stable Diffusion UI.cmd`.
If Windows SmartScreen prevents you from running the program click `More info` and then `Run anyway`.
## On Linux: 
Run `./start.sh` (or `bash start.sh`) in a terminal.

The installer will take care of whatever is needed. If you face any problems, you can join the friendly [Discord community](https://discord.com/invite/u9yhsFmEkB) and ask for assistance.

# Step 3: There is no Step 3. It's that simple!

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

# Easy for new users, powerful features for advanced users
## Features:

### User experience
- **Hassle-free installation**: Does not require technical knowledge, does not require pre-installed software. Just download and run!
- **Clutter-free UI**: A friendly and simple UI, while providing a lot of powerful features.
- **Task Queue**: Queue up all your ideas, without waiting for the current task to finish.
- **Intelligent Model Detection**: Automatically figures out the YAML config file to use for the chosen model (via a models database).
- **Live Preview**: See the image as the AI is drawing it.
- **Image Modifiers**: A library of *modifier tags* like *"Realistic"*, *"Pencil Sketch"*, *"ArtStation"* etc. Experiment with various styles quickly.
- **Multiple Prompts File**: Queue multiple prompts by entering one prompt per line, or by running a text file.
- **Save generated images to disk**: Save your images to your PC!
- **UI Themes**: Customize the program to your liking.
- **Organize your models into sub-folders**

### Image generation
- **Supports**: "*Text to Image*" and "*Image to Image*".
- **14 Samplers**: `ddim`, `plms`, `heun`, `euler`, `euler_a`, `dpm2`, `dpm2_a`, `lms`, `dpm_solver_stability`, `dpmpp_2s_a`, `dpmpp_2m`, `dpmpp_sde`, `dpm_fast`, `dpm_adaptive`
- **In-Painting**: Specify areas of your image to paint into.
- **Simple Drawing Tool**: Draw basic images to guide the AI, without needing an external drawing program.
- **Face Correction (GFPGAN)**
- **Upscaling (RealESRGAN)**
- **Loopback**: Use the output image as the input image for the next img2img task.
- **Negative Prompt**: Specify aspects of the image to *remove*.
- **Attention/Emphasis**: () in the prompt increases the model's attention to enclosed words, and [] decreases it.
- **Weighted Prompts**: Use weights for specific words in your prompt to change their importance, e.g. `red:2.4 dragon:1.2`.
- **Prompt Matrix**: Quickly create multiple variations of your prompt, e.g. `a photograph of an astronaut riding a horse | illustration | cinematic lighting`.
- **1-click Upscale/Face Correction**: Upscale or correct an image after it has been generated.
- **Make Similar Images**: Click to generate multiple variations of a generated image.
- **NSFW Setting**: A setting in the UI to control *NSFW content*.
- **JPEG/PNG output**: Multiple file formats.

### Advanced features
- **Custom Models**: Use your own `.ckpt` or `.safetensors` file, by placing it inside the `models/stable-diffusion` folder!
- **Stable Diffusion 2.1 support**
- **Merge Models**
- **Use custom VAE models**
- **Use pre-trained Hypernetworks**
- **UI Plugins**: Choose from a growing list of [community-generated UI plugins](https://github.com/cmdr2/stable-diffusion-ui/wiki/UI-Plugins), or write your own plugin to add features to the project!

### Performance and security
- **Fast**: Creates a 512x512 image with euler_a in 5 seconds, on an NVIDIA 3060 12GB.
- **Low Memory Usage**: Create 512x512 images with less than 3 GB of GPU RAM, and 768x768 images with less than 4 GB of GPU RAM!
- **Use CPU setting**: If you don't have a compatible graphics card, but still want to run it on your CPU.
- **Multi-GPU support**: Automatically spreads your tasks across multiple GPUs (if available), for faster performance!
- **Auto scan for malicious models**: Uses picklescan to prevent malicious models.
- **Safetensors support**: Support loading models in the safetensor format, for improved safety.
- **Auto-updater**: Gets you the latest improvements and bug-fixes to a rapidly evolving project.
- **Developer Console**: A developer-mode for those who want to modify their Stable Diffusion code, and edit the conda environment.
