	This page contains various links to tutorials and information on the Firmware. While Didj was vastly different, it can be upgraded to run the new Linux version. This is recommended as most of the Linux work is being done with the latest firmware version. You can find links to older version information in the depreciated section. The updated firmware versions usually end up including whats been added, so often times it will be easier to just move to the latest, but they are there if you need them.
