elvees/linux ? reverse-engineered prompt

I need help getting this ELVEES Linux kernel source to build for one of the supported boards.

Please figure out the right branch for either MCom 02 or MCom 03, and set up clear build instructions so I can compile it on a normal Linux machine without guessing. If there are any missing pieces, look up the current kernel docs online if you need to, then make the repo easier to use by adding a simple guide for choosing the branch, configuring the kernel, building it, and finding the output files.

I also want the README to be easier to understand for someone who is not deep into kernel work, so explain which branch is the main supported one, what the older branches are for, and any important warnings about this being a read only mirror with no pull requests. If possible, include a basic example for building an image for the supported hardware.
