here. here. this guys walks the talk. his ability to document the process is very helpful to people who want to get involved and support open source projects but are technically challenged and don't know where to start or how to use the tools, like google, to self-diagnose when something doesn't work right.
i know cuz i have read a lot of what has been written about that project. the medium blog post, for instance, is a keeper.
if you are looking for an exemplar of what a good open source project looks like, start with that, but there are other fantastic open source communities you can use as an example. one that comes to mind off the top of my head -- joomla. but there are many, many more. take projects that are posted on github - which by the way has done a fantastic job of building community in the oss ecosytem -- plus the projects_qua_repositories posted in this space are goldmines of sharing and giving back.
like i said, the best oss projects are fully documented and provide lots of walk-throughs, tutorials and problem-solving fora to provide (non-judgemental) helping hands to n00bs and get them started. you couldn't ask for more.
