In order to provide a consistent development environment between team members as well as making it easier to do physical pair programming sharing a .gitconfig is a good thing to do. After all, when using another person’s machine there are few things more annoying than not having access to the same shortcuts you rely on.

Git aliases are one of the easier consistencies to bring to a developer’s machine. This is how you can achieve a shared .gitconfig.

Add a .gitconfig to the repository. This is one I often start with.

[core]
    autocrlf = true
[alias]
    st = status
    hist = log --pretty=format:'%h %ad | %s%d [%an]' --graph --date=short
    ci = commit
    com = checkout master
    b = branch
    cob = checkout -b
    co = checkout
[push]
    default = simple

Once the .gitconfig is in the repo Git needs to be told to use it.

To do that add:

[include]
  path = ../.gitconfig

To the config file located in the Git directory i.e. .git/config.

The manual step not withstanding you now have a .gitconfig all members of the team should be using. It is a good idea to include this information in the project’s README.md. And if you were so inclined it could be automated if the project had some setup scripts to run.
