# git-config Settings You Want
Git comes with some fairly [lkml](http://www.tux.org/lkml/)-specific configuration defaults. You should fix this. All of the items below can be set either for your entire login account (`git config --global`) or for a specific repository (`git config`).
Full documentation is under `git help config`, unless otherwise stated.
* `git config user.name 'Your Full Name'` and `git config user.email 'your-email@example.com'`, obviously. Git will remind you about this if you forget.
* `git config merge.defaultToUpstream true` - causes an unqualified `git merge` to merge the current branch's configured upstream branch, rather than being an error. This makes `git merge` much more consistent with `git rebase`, and as the two tools fill very similar workflow niches, it's nice to have them behave similarly.
* `git config rebase.autosquash true` - causes `git rebase -i` to parse magic comments created by `git commit --squash=some-hash` and `git commit --fixup=some-hash` and reorder the commit list before presenting it for further editing. See the descriptions of “squash” and “fixup” in `git help rebase` for details; autosquash makes amending commits other than the most recent easier and less error-prone.
* `git config branch.autosetupmerge always` - newly-created branches whose start point is a branch (`git checkout master -b some-feature`, `git branch some-feature origin/develop`, and so on) will be configured to have the start point branch as their upstream. By default (with `true` rather than `always`) this only happens when the start point is a remote-tracking branch.
* `git config rerere.enabled true` - enable “reuse recorded resolution.” The `git help rerere` docs explain it pretty well, but the short version is that git can record how you resolve conflicts during a “test” merge and reuse the same approach when resolving the same conflict later, in a “real” merge.
## For advanced users
A few things are nice when you're getting started, but become annoying when
you no longer need them.
* `git config advice.detachedHead` - if you already understand the difference between having a branch checked out and having a commit checked out, and already understand what “detached head” means, the warning on every `git checkout ...some detached thing...` isn't helping anyone. This is also useful repositories used for deployment, where specific commits (from tags, for example) are regularly checked out.
