+## HOWTO manage sponsors
+
+Gitea sponsors who donate the [minimal required amount for Gold](https://opencollective.com/gitea) have, during a year:
+
+* Their logo is displayed on GitHub
+* Their logo is on the gitea.io home page
+
+This is done by:
+
+* Adding their logo to the themes/gitea/static/images directory
+* Adding a link with their logo to the home page at themes/gitea/layouts/home/index.html
+
+The date of the addition must be recorded with a reminder to verify
+the sponsorship has been renewed at the anniversary date. If not the links and logo can be removed.
+
+Note that the `themes` directory is [located in another repository](https://gitea.com/gitea/theme) and that updates
+are only deployed when the [website](https://gitea.com/gitea/website) repository is updated.
