 - Make sure any new code files have a license header.
 - Submit a pull request to the original repository.

+# Acceptance policy
+
+These things will make a PR more likely to be accepted:
+
+ * a well-described requirement
+ * tests for new code
+ * tests for old code!
+ * new code follows the conventions in old code
+ * a good commit message (see below)
+
+In general, we will merge a PR once two maintainers have endorsed it.
+Trivial changes (e.g., corrections to spelling) may get waved through.
+For substantial changes, more people may become involved, and you might get asked to resubmit the PR or divide the changes into more than one PR.
