> v2: update wording per Leif's and others' comments REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1910
A section 'Submodules' is added to clarify the submodule policy in edk2 repo. Git commands are also added to show the correct way to clone submodule repos, in which '--recursive' is removed because it's not needed but recommended in other document.
