Tutorial - request for feedback

Hello folks, accordingly to http://news.php.net/php.doc/969384950 I managed to finish first draft of tutorial for new PHP Manual contributors. It covers the most important topics (in my opinion), but it of course require improvements. First of all, I need some linguistic support. My English level is poor and any help on making it less broken is aprecciated. I am also relatively new member so this resource may contain meritorical errors. Not finished parts at the moment: - style guidelines - I would need some mentoring here as I don't really know this topic; just summarize Fedora Doc Style Guide here? - PhD docs - not finished yet, but I'm working on it Technical backend, so parsing files and integrating it with doc.php.net, is also not ready yet, but I will commit it soon. It should be simple work. Here is the code: https://github.com/php/web-doc/tree/master/tutorial Feedback or just changes/PRs to this repository are welcome! Thanks in advice, Maciej.
