Seeking guidance for contribute in FreeBSD

[Saurabh Sihag]

Hello Everyone,
I am Saurabh Sihag, new to the developers world. I would like to start
contributing to open source and start working FreeBSD.
I am highly proficient in C++/C, python and Docker(for deployment).
Can you suggest me the skills I should start working on so that i can start
contributing in FreeBSD, also some good beginners bug.
Thank you
