-     *  donate button which allows for making a donation to support CryptPad development.
+     *  subscribe button which allows them to upgrade to a paid account. We handle payment,
+     *  and keep 50% of the proceeds to fund ongoing development.

-     *  You can either:
-     *    A: Leave it exactly as it is.
-     *    B: Hide the donate button.
-     *    C: Change the donate button to a subscribe button, people who subscribe will get more
-     *       storage on your instance and you get 50% of the revenue earned.
