+# {{< icon "fa fa-heart heart" >}} Sponsor the rclone project
+
+Rclone is a free open-source project with thousands of contributions
+from volunteers all round the world and I would like to thank all of
+you for donating your time to the project.
+
+However, maintaining rclone is a lot of work - it is **my full time
+job**. Nothing stands still in the world of cloud storage. Rclone
+needs constant attention adapting to changes by cloud providers,
+adding new providers, adding new features, keeping the integration
+tests working, fixing bugs and many more things!
+
+I love doing the work and I'd like to keep doing it - your support
+helps make rclone possible.
+
+Thank you :-)
