Willing to contribute? Join Sunrise
Ok, I know that there are some people out there who maintain several ebuilds on their private overlays. Also, there are some others that keep attaching new ebuilds on our bugzilla. But few of them know that Gentoo offers an official overlay for users to contribute ebuilds. That is Sunrise. Either you are familiar with ebuild writting or not , all you have to do is reading HowToCommit guide, answer a simple question, get your password, and start commiting any ebuild you like :) . For those who dont know much about ebuild writting, there are developers on #gentoo-sunrise channel ( freenode network ) who are willing to help you and teach you how to write proper ebuilds :) .
ps (tip): Note that many developers are looking for new ebuilds on sunrise, so if you want your shiny ebuild to reach the portage tree ( as quick as possible ) , sunrise is the answer :)
