In the wiki page here on Github, as well as in the README.md file, of course, which is the same, there are 14 occurrences of "it's".
2 of them are correct and mean "it is", as they should. ("[…] it's possible that you'll miss […]" and "It's a great psychological trick […]"
All of the other 12 are incorrect, and should be changed to "its". (I won't list them all here.)
