 # gh-action-bot
 
-Action bot for Github. Checks a repo's event stream and leaves a ghost comment when your criteria is met.
+Action bot for Github.
 
 [![GitHub license](https://img.shields.io/badge/license-MIT-blue.svg)](https://raw.githubusercontent.com/w33ble/gh-action-bot/master/LICENSE)
-[![Project Status](https://img.shields.io/badge/status-stable-green.svg)](https://nodejs.org/api/documentation.html#documentation_stability_index)
-
-## Usage
-
-`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
-
-`yanr run clean owner/repo pr_number`: removed any comments that match the owner and body requirements
-
-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`.
