 Tests for fbchat
+~~~~~~~~~~~~~~~~
 
 To use these tests, put:
 - email
 - password
 - a group_uid
-- a user_uid whom will be kicked from that group and then added again
+- a user_uid (the user will be kicked from the group and then added again)
 (seperated these by a newline) in a file called `tests.data`, or type them manually in the terminal prompts
 
 Please remember to test both python v. 2.7 and python v. 3.6!
 
 If you've made any changes to the 2FA functionality, test it with a 2FA enabled account
+If you only want to execute specific tests, pass the function names in the commandline
