You don't have to do anything besides turning it on. If a conflict has been resolved before, somehow it remembers that and applies the fix. The only pitfall I've seen is if you fix the conflict erroneously, it will remember that too.

Yes, my general rule of thumb as a rerere user and devotee is to at the very least do a test build before git-add'ing your resolved files. You won't catch logical errors, but you will catch syntactical issues that came up during conflict resolution. It helps, a bit.

If you accidentally record an incorrect resolution, you can also run `git rerere clear` to clear the cache, or `git rere forget <path>` to forget resolutions just for a particular file.

Yeah, I learned about this last weekend, after mistakenly trying to rebase a repo where we generally merge.

I don't think that rerere offers fine grained enough control over "forgetting". What I needed (until I realized my mistake) was a way to clear any memory of a resolution for the current conflict in path.
