 ## Scripts
 
+### Reddit Comment and Post Deleter
+This script deletes all comments for a given user that are older than 2 years old. To properly configure, please
+create the following environment variables: `REDDIT_USER_ID`, `REDDIT_USER_PASSWORD`, `REDDIT_APP_ID`, `REDDIT_SECRET`.
+
+For information regarding the acquisition of values for the above environment variables, please 
+check here: [Link](https://github.com/reddit-archive/reddit/wiki/OAuth2-Quick-Start-Example#first-steps).
+
 ### Slack Message Parser
