+## Sponsors
+
+If you find Tocbot useful, consider supporting it by becoming a sponsor. You can do this by visiting [the tocbot repo on github](https://github.com/tscanlin/tocbot) and clicking the "Sponsor" button at the top of the page. This will help me continue to develop and maintain Tocbot. Sponsors that contribute $5 /month or more will have their logos shown below. Thank you!
