 it finds twitter links and turns them into girlcock links for better embed
 
+# setup

 ## easiest way
 
 docker image published at `git.cesium.one/kira/cockinator:latest` only needs `DISCORD` passed as a variable with your token
 
 ### examples
 
-`docker run -e "DISCORD=TOKEN_HERE" git.cesium.one/kira/cockinator:latest`
+```
+docker run -e "DISCORD=TOKEN_HERE" git.cesium.one/kira/cockinator:latest

+
+or if you like docker compose:
 
 ```yml
 services:
   bot:
-    restart: unless-stopped
     image: git.cesium.one/kira/cockinator
     environment:
       - DISCORD=TOKEN_HERE

 you can also build the image with docker-compose, by replacing `image: git.cesium.one/kira/cockinator` with `build: .`
 
 ## the config file

+### avatar rotation
+
+if you add images to `./avatars` (`/app/avatars` in the docker container), the bot will shuffle them all and cycle through daily. this will work without `config.json`, but can be configured further using it. for docker, you can mount `./avatars` to the container by adding `-v ./avatars:/app/avatars` to the docker run command
