I wanna to do Gsoc this year by contributing to some C++ libraries and I am beginner.

Actually, I want to contribute by modifying libraries

I have once made some part of String library by myself using OOPS

I have talked at IRC channel and according to my interest someone suggested me to contribute to https://github.com/boostorg/algorithm

Can some one help me out how should I continue ?

How to use git-hub here for contribution and bug fixing ?

Regards,

Aman
