As I've been git-ifying some stuff around here, I've run into a few tips that might be useful for other git beginners.

The first is to setup some global options, some of which are nice for folks coming from Subversion. Having a global ignore file is useful. Mine has the following contents:

*~
*.orig
*.rej
*.swp
.#*
*.o
.DS_Store

Then adjust some global git options:

$ git config --global core.excludesfile ~/.gitignore
$ git config --global alias.st status
$ git config --global alias.ci commit
$ git config --global alias.co checkout
$ git config --global alias.br branch
$ git config --global user.name "Your Name"
$ git config --global user.email you@example.com
$ git config --global core.editor "vim"
$ git config --global color.branch auto
$ git config --global color.diff auto
$ git config --global color.interactive auto
$ git config --global color.status auto

The last few allow for colorized output, which I like (makes things like git status easier to read).

I also found out that I had screwed up the remote origin when setting up a new repository, and didn't want to re-do everything, so found this useful one-liner:

$ git remote rm origin

Git n00bs like me will appreciate the above. =) (Note to self, express git urls as ssh://git.remote.com/path/to/repo.git rather than ssh://git.remote.com:/path/to/repo.git!)

Finally, I found an excellent resource called Create a new Git Remote Repository from some local files (or local git repository). Very accurate, very clear, and very easy to follow. Essentially I was taking a 4GB set of documents and wanted to turn it into a remote repository so that I could push/pull from my laptop and using this article, I was able to do so easily.
