 # StickerSetHandler
 
-Send sticker to this bot to form your own stickers set. Send /delete to delete this sticker set
+A bot that builds and manages a personal sticker set for each user from stickers they send.
 
-## How to run
+## Functionality
+
+When a user sends a sticker, the bot extracts its emoji and adds it to a per-user sticker set
+named `<user_id>_by_<bot_username>`. If the set does not yet exist, it is created first. The bot
+supports regular, mask, and custom emoji sticker sets, determined by the type of the first sticker
+added. Sending `/delete` removes the user's entire sticker set.
+
