+## Maintainer's Guide ##
+
+(These notes are mostly only for people merging in pull requests.)
+
+**First and foremost, try to maintain a clean, linear git history.**  With very
+few exceptions, running `git log` should not show a bunch of branching and
+merging.
+
+Never use the GitHub "merge" button, since it always creates a merge commit.
+Instead, check out the pull request locally ([these git aliases
+help][git-aliases]), then cherry-pick or rebase them onto master.  If there are
+small cleanup commits, especially as a result of addressing code review
+comments, these should almost always be squashed down to a single commit.  Don't
+bother squashing commits that really deserve to be separate though.  If needed,
+feel free to amend additional small changes to the code or commit message that
+aren't worth going through code review for.
+
+If you made any changes like squashing commits, rebasing onto master, etc, then
+GitHub won't recognize that this is the same commit in order to mark the pull
+request as "merged".  So instead, amend the commit message to include a line
+"Fixes #0", referencing the pull request number.  This would be in addition to
+any other "Fixes" lines for closing related issues.  If you forget to do this,
+you can also leave a comment on the pull request [like this][rebase-comment].
+If you made any other changes, it's worth noting that as well, [like
+this][modified-comment].
+
+If this is the first pull request from a new contributor, make sure they've
+signed a CLA and then add them to the AUTHORS and CONTRIBUTORS file.  If they
+are contributing on behalf of a company, the individual goes in CONTRIBUTORS and
+the company goes in AUTHORS.  Contributors should never add themselves to these
+files.  If they try to, don't merge that commit.  These files should only ever
+be modified by project maintainers so that the git history of these files
+identifies who actually did the CLA verification.
