 ## Donate
 
-If my work on river adds value to your life and you'd like to support me
-financially you can find donation information [here](https://isaacfreund.com/donate/).
+Unfortunately, the current pace of river's development is not sustainable
+without more financial support. If my work on river adds value to your life
+please consider setting up a recurring donation through [liberapay]. You can
+also support me with a one-time or monthly donation on [github sponsors] or
+[ko-fi] though I prefer liberapay as it is run by a non-profit. Thank you for
+your support!
