If you're on Linux, OSX or FreeBSD this should help you get 
started:

On Windows the part about `git` is the same, however I'm not sure 
about the additional tools like `make`. I would try getting them 
using `msys2`'s `pacman` package manager, though maybe the `make` 
distributed with DMC/DMD is specifically needed for DMD, phobos 
and druntime. This was written in more detail here:
http://wiki.dlang.org/Building_DMD, however I'm not sure if the 
information is up to date.

Anyway, here you can find a good overview of the procedures (i.e. 
making Pull Requests on github):
