+Changelog
+~~~~~~~~~
+
+All changes, even minor ones, need a corresponding changelog
+entry. These are managed by Towncrier
+(https://github.com/hawkowl/towncrier).
+
+To create a changelog entry, make a new file in the ``changelog.d``
+file named in the format of ``issuenumberOrPR.type``. The type can be
+one of ``feature``, ``bugfix``, ``removal`` (also used for
+deprecations), or ``misc`` (for internal-only changes). The content of
+the file is your changelog entry, which can contain RestructuredText
+formatting. A note of contributors is welcomed in changelogs for
+non-misc changes (the content of misc changes is not displayed).
+
+For example, a fix for a bug reported in #1234 would have its
+changelog entry in ``changelog.d/1234.bugfix``, and contain content
+like "The security levels of Florbs are now validated when
+recieved over federation. Contributed by Jane Matrix".
