Now write in his chat "!help" or "!commands"
You will find a list of commands that you can write:

• !price - see the current rates

• !check - see how many sets the bot has that you can craft

• !sell X - sell sets for X cs:go keys
  
• !sellgems X - sell X sets for gems

This is not a 24/7 bot so sometimes it can be offline. If that happen, send a friend request and when it will be back it will automatically accept the friend request and it will send you a message
