Installing.
You'll need to create a .cfg file with a number from 0 to 10.

In our example here we'll pick TF2. The directory of the config files are
a:\Users\name\AppData\Roaming\lithium\team fortress 2\

If you wish to make your config a part of 0.cfg then open the file up in notepad and ( ͡ ͜ʖ ͡) the config of your choice and save. Other wise, open notepad and ( ͡ ͜ʖ ͡) the config of your choice click save as and make sure the save as type is "all files" then give it a number from 0 to 10 and the extension needs to be .cfg

Sharing
Note: If you need to see what config you were using a window in the config tab will tell you the number of the config.
