github - How do I pull from git repo, when using --separate-git-dir -

i setup project on internal testing server using git clone ( --separate-git-dir tag).

i'd update project git pull can few updates i've made , pushed repo.

when login server - should going 'separate-git-dir' , running 'git pull' directory - or running 'git pull' directory project installed to?

the structure looks this:

|-git repo | |-public_html     |-this documents git live     |-folder2, etc.     |-index.html     |
