Minetest core is a volunteer effort, but the barrier to entry is too high. In a series of changes meant to lower that, we're going to hold an event meant to help people understand the engine: A documentation sprint!
What: Documentation sprint for Minetest
Where: #minetest-doc on Freenode and http://dev.minetest.net
When: 2013-01-19 16:00 UTC to 2013-01-20 01:00 UTC
Come in to the channel, chat about the game, read some code, and write (or edit!) helpful documentation. Not a coder? That's fine, too! Document things about the community, how to create texture packs, or even how to write and edit documentation (meta-meta-documentation is probably not necessary).
We hope to achieve a more complete guide to contributing to the game engine, as well as being part of the community. We may not finish it that day, but it will sure be a great start!
Postscript: We could also meet up in real life in the Bay Area, if anyone is interested.
