Documentation improvements

[lucaaamaral]

This project lacks proper documentation. I was hoping I could use this tool instead of srsRAN to conduct my tests with Magma core.
The only outputs I got from compiling this project was the .so files.
Seems like #38 improves the documentation but has never been merged.

Hi, I’d like to work on improving the documentation for this project.
Please assign this issue to me.
