Howto forward workdir to HEAD

Hi,

I'm trying to setup an intranet Webapp using GIT for maintanance and backup. First I created a git repo on my working machine and imported the webapp, made some changes.

Then I created a normal, non-bare repo at the server and pushed from my local repo into the server repo, checked out branch "stable" and everything is fine.

Now I made a local change and pushed again, but the servers workdir is not automatically forwarded to the pushed state. How do I forward it?

Can I define a Hook that automatically forwards the workdir after a push, but only if the workdir is clean?

What do you think of this method to deploy a webapp?

Best regards,
