[x265] x265: How to get started (newbie question)?

[Krishna]

Thanks Steve! I will get the spec and start studying the code and the
various commits over the past few days. Hopefully, soon enough I will be
comfortable with the code and I can then give back something meaningful to
the project!

Have a good time at IBC!

Regards,
Krishna
