As it is with any Open Source project, the SIMPL project can only grow and prosper if the people using the code give something back in return.
If you are an experienced LINUX developer or kernel hacker we certainly could use your contributions.
Our code is written with the KISS philosphy in mind. As such even a novice C programmer could study and understand the code. So even if you are just starting out as a LINUX developer your contribution to this effort is welcome. We will make every reasonable effort to help you get going and support you along the way.
There is an online course available from iCanProgram.com which teaches the basics of LINUX programming the SIMPL way.
