+Typo fixes
+==========
+
+Fixing typos and grammatical errors in documentation is a welcome
+contribution that does not require a linked issue. The most appropriate
+places for such fixes are:
+
+* The ``Doc/`` directory (end-user documentation)
+* Internal documentation, such as files in ``Misc/``
+* News entries under ``Misc/NEWS.d/``
+
+Keep typo-fix PRs **small and focused**, ideally limited to one file or a
+small set of closely related files. Large PRs that touch many unrelated files
+notify a large number of reviewers unnecessarily and are harder to review.
+Large typo-fix PRs, or PRs touching directories outside those listed above,
+may be closed with a reference to this section.
