 ### Caveats
 
-This is a WIP. Heres some things you might expect to work that don't. Plus some other things I should mention.
+This is a WIP and mainly meant for my personal use. Heres some things you might expect to work that don't. Plus some other things I should mention.
 
-- Only lists contacts and groups that have been messaged on phone
-- Only fetches a few messages for last contacted
-- To display names they have to be entered through the `/name` or `/addname` commands for each contact
-- No support for images, videos, documents etc
+- Only shows existing chats
+- Only fetches a few old messages
 - No incoming message notification / count
-- Not configurable at all
-- Leaves its config files in your home folder
-- FaceBook obviously doesn't endorse or like these kinds of apps and they're likely to break when they change stuff in their web app
+- No proper connection drop handling
+- No uploading of images/video/audio/data
