Wow... I just looked at the site in a little more detail. Much of it is in "maintenence mode" (specifically, the documentation, issues, and pull requests, source code), so there's very little operational information to work with. There doesn't appear to be a forum, eitther (at least not linked off the main page), so everything is mailing list based (and even that doesn't work -- the listserve site cannot be reached). There are very few supported targets, as well, which means a limited addressable 'market', thus fewer users, which means less momentum/impitus for development... all this to say, that platform has the obscurity/niche element that Macintosh users faced in the mid 1990's (when the company was about to go bankrupt and marketshare was <4%).
So, @bbxe3zfcle -- if you plan to use LibreCMC, realize that you are likely on your own for most of what you will want to do.
