[Outreachy] Introduction

Hello everyone,

My name is Sangeeta and I’m one of the Outreachy applicants. I would like to work on the microproject "Unify the meaning of dirty between diff and describe".

While looking at the files for `describe` and `diff` commands I found that the `describe.c` is present in builtin[1] folder whereas diff.c is found in the root[2] folder as well as builtin[3] folder. I could not find any implementation of --dirty in the diff.c present in builtin[3] folder. So is it that I have to compare the implementation of describe.c[1] and diff.c(of root folder)?

Also, I was curious to know why is there a builtin folder when many commands described in that are described again in the root folder?

Looking forward to working with you all.
