+### Picking up abandoned pull requests
+
+Sometimes, contributors send a pull request, but later find out that they don't have enough
+time to work on it, or they simply are not interested in it anymore. Such PRs are often
+eventually closed and they receive the `S-inactive` label. You could try to examine some of
+these PRs and pick up the work. You can find the list of such PRs [here][abandoned-prs].
+
+If the PR has been implemented in some other way in the meantime, the `S-inactive` label
+should be removed from it. If not, and it seems that there is still interest in the change,
+you can try to rebase the pull request on top of the latest `master` branch and send a new
+pull request, continuing the work on the feature.
