+- `LOG_LEVEL` - [Log level](https://deno.land/std@0.201.0/log/mod.ts?s=LogLevels). Default: `INFO`.
 
 ## Running
 
 - Start stable diffusion webui: `cd sd-webui`, `./webui.sh --api`
 - Start bot: `deno task start`
 
+To connect your SD to the bot, open the [Eris UI](http://localhost:5999/), login as admin and add a
+worker.

 ## Codegen
 
 The Stable Diffusion API in `app/sdApi.ts` is auto-generated. To regenerate it, first start your SD
