 # cringebot
 `cringebot` is a bot that tracks and auto-deletes on Mastodon/Pleroma accounts according to a set maximum age, if they are bad enough. Tracking multiple instances simultaneously is possible. Once a status is flagged for retention, the bot will not check it again.
 
+*Note: This software is still a little rough around the edges, especially when it comes to first-time setup.*

 ## Installation (Linux)

+#### Learning
+
+The bot will respond to each of your messages with a categorisation direct message. To adjust it, you can respond to this direct message with:
+
+```
+learn spam
+learn ham
+
+unlearn spam
+unlearn ham
+
+relearn spam
+relearn ham
+```
+
+Use `learn` on messages the bot is unsure about, `unlearn` to weaken the categorisation, and `relearn` to nudge a clear categorisation one way or another. When a message is learned or relearned as spam, it's scheduled for deletion `max_age` minutes after it was posted. When it's learned or relearned as ham, or unlearned as spam, it's removed from the deletion schedule.
