Use me to easily level up your steam account! To use this service, add the bot to friends and use the following commands in a chat message:

!buy # = buy sets for # number of keys e.g. !buy 5
!check = show how many sets you can buy in total
!check # = find out how many sets you can buy for a specific amount of keys e.g. !check 10
!level # = calculate how many card sets/keys it takes to reach a certain level e.g. !level 100
!help = display help menu
