# Basic Usage of SwarmUI

So you want to know how to get started with SwarmUI, huh? It's easy!

For the most part, just download the installer and follow the instructions on screen. Everything explains itself, even the settings and parameters all have `?` clickables that explain what they do!

Nonetheless, here's a step-by-step you can follow:

## Installing

Step one: [Install SwarmUI](/README.md#installing-on-windows).

Once you've ran the basic program-installation, if all went well, it will open a web interface to select basic install settings.
- It starts with an option to skip the installer and use defaults. New users might prefer this. Otherwise:
    - Pick a theme (I think default is best, but you got options)
    - Pick who the UI is for (usually just Yourself or Yourself on LAN)
    - Pick what backend(s) to install. If you already have ComfyUI or another backend you can skip this - if not, pick one. I recommend ComfyUI for local usage.
        - If you already have a Comfy install and want to use it, this is not recommended for most users, but:
            - you can select no backend in the install page
            - and then add your existing install in the main UI later via `Server`->`Backends`->add a `ComfyUI Self-Starting`->give it your comfy `main.py` path->`Save`
            - you'll also want to edit `Server Configuration`->`Model Root` to be your existing comfy models dir, and change `SDModelFolder` to `checkpoints` to match Comfy's folder format.
    - Pick any starter model(s) you want to download. If you already have some you can skip this.
- Confirm you want the settings you selected, and install.

Once this is done, it should automatically redirect you to the main interface.

(You can close the server at any time by just closing that console window it pulls up or via `Server`->`Shutdown`, and you can start it again via the desktop icon, or the `launch` script in the folder).

## Configuring

If you have pre-existing Stable Diffusion files, you'll want to configure settings a bit. If not, the defaults are probably fine.
- If you have an Auto WebUI or ComfyUI folder with models in it, go to the `Server` tab then `Server Configuration` and set `ModelRoot` to the path to your UI's `models` dir, and set `SDModelFolder` to `Stable-diffusion` for Auto WebUI or `checkpoints` for ComfyUI.
- Be sure to click the 'Save' button at the bottom when you're done (only visible if you've edited any settings)

## Your First Image

- Open the `Generate` tab at the top
- At the bottom, there's a `Models` tab, click that
    - on the left, there's a folder tree. Click into the folder you want. If this is a fresh install and you downloaded the official models, there's exactly one `OfficialStableDiffusion` folder here.
    - there's now a model listing. Click the icon of the model you want. (You can also change the view between cards/thumbnails/list)
    - You can also click the name of the model in the info bar just above those bottom tabs, and you'll get a quick-dropdown list of models, if you prefer that.
    - You can also click the bar separating the bottom tabs from the main area above it, and drag it down, to get it out of your way.

- Now, in the bottom-center, there's a text box that says `Type your prompt here...` - type something nice into this box, like `a photo of a cat`
- Next either hit Enter, or click the purple `Generate` button

- If all went well, you should have a nice picture of a cat in the center of your screen!

If it didn't go well, there's usually an error message telling you what went wrong, if not check `Server` -> `Logs` tab. If you can't figure it out, open an [issue here](https://github.com/mcmonkeyprojects/SwarmUI/issues) or ask on [discord](https://discord.gg/q2y38cqjNw).

## Using A Refiner / Upscaling Images

So, you want *refined* images, huh? Well, if the first pass of generation is enough, you can use the Upscale/Refine options.

- Just open the `Refine / Upscale` parameter group (you might have to scroll down if your screen is small - it's right below `Init Image`), and toggle the checkbox next to the group title.
- If you have a dedicated refiner model, Enable the `Refiner Model` parameter and select your model
- If you want to upscale, drag the `Refiner Upscale` over to `1.5` or `2`. If you're using a DiT model (eg SD3 or Flux), enable `Refiner Do Tiling`
- Set the other parameters however you want. Click the `?` if you're not sure what a parameter does.
- Click Generate! Yup that's literally all you have to do. Easy, huh?
- You can turn it off at any time by toggling the toggler on the group (right next to where it says `Refiner` as the group label).

## Getting Advanced: Playing With Parameters

SwarmUI is designed on the principle of exposing all the parameters to you, but making them approachable. To that end:
- All the parameters are grouped. You can toggle groups open/closed, and where relevant there's sliders to toggle groups on/off.
- All the parameters have a lil purple `?` icon next to them. Clicking this will open a popup with an explanation of the parameter and some examples.
- When in doubt, with most parameters, just play with them and see what happens. Lock in your `Seed` to a constant one before trying to avoid unrelated changes.

## More Than Text: Playing with Prompts

Prompting is, primarily, just text input. However, there are some special options also available (on both Prompt and Negative Prompt):
    - If using SDXL or UnClip, you can use *ReVision* by just dragging an image into the prompt box. This will have the model interpret the image (using ClipVision) and include it in the prompt.
    - You can do things like `<random:cat, dog>` to randomly select different options
    - You can type a `<` in the prompt box at any time to see some options
    - See [Prompt Syntax](/docs/Features/Prompt%20Syntax.md) for more

## We Gotta Go Faster: Add More Backends

You want more images more faster right now hurry up and tell me how quick quick quick? The Backends tab holds the key to your speedy needs.
- First, find some GPUs you can use.
    - The obvious choice is additional GPUs in your PC if you have any, but who has those? (If you have that ... first of all, Congrats! That's awesome! Second, you can absolutely use that)
    - Do you have other computers in your house? Maybe a second machine in the living room, or a laptop sitting around? If there's GPUs in em, they'll do!
    - Fan of Google Colab? That'll work!
    - Got some cash to spare? Rent a GPU server online (eg vastai, runpod, aws, etc).
    - Got close friends with GPUs? If you can figure out the network routing (and the interpersonal agreements), you can use those!
- Go to the `Server` -> `Backends` page
- Pick the backend type that you want, and click the button to add it.
    - For remote hosts, you'll want to set up SwarmUI over there, get a remote connection working, and then add `Swarm-API-Backend`, and give the URL to it.
    - For more GPUs in your one machine, you can eg use multiple `ComfyUI Self-Starting` and just change the GPU ID for each.
- If it doesn't error out, you can immediately start using it.
    - When you generate images, your first generation goes to the first backend, your second to the second one, etc.
    - If you generate very slowly, you might only use one backend. If you release a big batch, or spam the Generate button, or use a grid, or etc. it will spread across all backends automatically.
- You can of course edit or delete backends at will from that page. They will persist across restarts automatically.
- If you use custom comfy workflows, note that that comfy workflow tab only uses your first comfy instance - you'll only use all available backends once you use the `Use This Workflow` button and go back to the main `Generate` tab.

## Testing Like A Pro: The Grid Generator

What's the fun in testing changes one by one, when you can unleash your machine to test all of them and lay it out clearly for you? This is where the Grid Generator comes in!
- Go to the `Tools` tab at the bottom
- In the dropdown, select `Grid Generator`
- Optionally name your grid
- Use the dropdown to select an axis you want to compare
- Fill it with values yourself, or you can click the button on the right to fill with examples (where applicable)
- You'll notice a new axis box is available automatically. You can add as many as you want.
- When you're ready, click `Generate Grid` at the top - it replaced your `Generate Image` button
    - To get `Generate Image` back, swap the tool back to the blank space at the top of the tools list
- Click the output link to view your grid as it comes

## Combining Features

- Want to use [IP-Adapter](/docs/Features/ImagePrompting.md) image gen with an [Image-To-Video](/docs/Features/Video.md)?
    - No problem! Just... do both! Swarm is so easy it's crazy sometimes - you can just enable multiple different features at the same time, and generally trust Swarm will automatically figure out how to combine them appropriately.
    - If you ever find a case that doesn't work, you can just [file an issue](https://github.com/mcmonkeyprojects/SwarmUI/issues) to get that fixed.
