Function documentation

I’m the author of a free WordPress plugin and I’d like to add some features that are only available to patrons. I’m assuming this is possible by having the user install the Patreon plugin along side my plugin, but I’m having trouble finding the documentation for the functions I need to check patronage. I found this document on Dropbox that mentions some of the functions, and is probably enough to get me started, but is there any more documentation about these functions and how to use them? Thanks.

These two documents should help you greatly:

There may be some yet not documented. But you can easily detect all hooks by searching the plugin files with a file searching utility that checks for contents.
