Read the Plug'in documentation, which is intended for researchers, developers, operationals, etc. who are standing up experiments on top of Plug'in. The documentation can be edited by cloning a git repository.
If you find problems with content on the Plug'in documentation, log an issue against the correspondent atom project with the page that contains the bug. Hint: you can just dump useful text into a bug report, and the documentation team will format it and update the docs for you.
