 ## Notes
 
 - Quotes live in `quotes.db` (SQLite, created on first run, gitignored).
+- `!grabquote` reads an in-memory buffer of each user's last channel line;
+  that buffer is per-session and resets on reconnect. Grabbed lines are stored
+  as `<nick> message`. Bot commands are never recorded, so you can't grab one.
 - The bot auto-reconnects with exponential backoff and answers `PING`.
 - If the nick is taken it appends `_` and retries.
 - A NickServ password, if set via `IRC_NICKSERV_PASS`, is sent on connect —
