Hi, you can +2 it, I guess.
But I would like to point you to read some docs. :)
https://www.mediawiki.org/wiki/Manual:Coding_conventions/PHP for coding convention and https://www.mediawiki.org/wiki/Gerrit/Commit_message_guidelines for how-to format a commit message.
If you have any questions, be free to ask me or anyone else here.
Best regards, Zoran
