Where to begin depends a lot on what you want to do.

The developer site is designed to provide a reference for the various bits of hacking that are possible on the empeg -- but you're right, it's not organized with any sort of introduction or tutorial. If someone wanted to write such a thing, I would gladly include it.

Knowledge of C and Linux are probably essential; there's only a very little you can do otherwise. The config.ini details are documented in the player section of the dev site -- but keep in mind this only controls a small set of configuration options for Empeg Ltd's player software. It's not where you would generally do your own programming, although changing some of the settings may be helpful.

The best way to proceed is probably to pick a small project or idea, and learn as much as you can about all the components you would need to make it work.
