 ## Usage
 
-`node . owner/repo`
+`yarn start owner/repo`: watch the event stream and handle matches
+
+`yarn run force owner/repo pr_number`: force a comment on a specific pr, by number
 
 You'll need to set some environment flags. Check `sample-env` for what is available, and you can copy the file to `.env` in the root and add your settings there as well.
 
+### Personal Access Token
+
+You will need to provide a Github [Personal Access Token](https://github.com/settings/tokens/new). It will need `write:org` access in order to create comments.
+
+### Debugging
+
+If the script isn't doing what you expect, you can get more output from it by prepending the script with `DEBUG=1`.
