[coreboot] Introduction

[vaibhav]

Hello everyone, I am Vaibhav, a 2nd-year Electrical Engineering student,
willing to contribute to coreboot this summer.
Currently, I am intermediate in C and beginner in embedded systems
I have started with going through the documentation and setting up my build
environment,
could anyone please guide me in what other concepts I should start looking
into and how do I familiarize myself with coreboot and its codebase so that
I may be able to make valuable contributions.
