I am an undergraduate student. Recently, I've developed huge interest in Tor & thus would like to contribute to it by adding code to its projects. Problem is, I don't know much about contributing to open source & that's where I would like you to help me. I have expert skills in C/C++ & shell scripting. 

Can you please help me with these things ?

1. Finding me appropriate mentor & project given my technical skills.

2. Guiding me about the prerequisites I should fulfill before I can start contributing to Tor.

Hope to see a good response.
