» What are badges?A set is all the cards needed to craft a badge once.
A badge is an icon on your profile (and tied to your account) that represents the trading card sets you've collected or your participation in an event.
Read about Steam Trading Cards on the official page.

» Do I need to own the game to craft its badge?No, you may craft badges from games you don’t own.

» How to use the bot?Add the bot to your friends list and type the command you want via Steam Chat.
You don't need to send a trade offer or do something else, just send the command and let the bot take care of the rest.
List of all commands you can see by using a command “!help" or "!commands".

» Do I need to deposit anything? How do I know it's safe?You don't have to deposit anything. Everything is done through Steam and you may always check the trade offer you received before accepting it.
Also, if you change your mind, you may decline the trade offer at anytime.
