+## Sponsors
+
+`hexyl` development is sponsored by many individuals and companies. Thank you very much!
+
+Please note, that being sponsored does not affect the individuality of the `hexyl`
+project or affect the maintainers' actions in any way.
+We remain impartial and continue to assess pull requests solely on merit - the
+features added, bugs solved, and effect on the overall complexity of the code.
+No issue will have a different priority based on sponsorship status of the
+reporter.
+
+Contributions from anybody are most welcomed.
+
+If you want to see our biggest sponsors, check the top of [`README.md`](../README.md#sponsors).
