+Support kitty development
+===========================
+
+My goal with |kitty| is to move the stagnant terminal ecosystem forward.  To that
+end kitty has many foundational features, such as: :doc:`image support
+<graphics-protocol>`, :doc:`superlative performance <performance>`,
+:doc:`various enhancements to the terminal protocol <protocol-extensions>`,
+etc. These features allow the development of rich terminal applications, such
+as :doc:`Side-by-side diff <kittens/diff>`, :doc:`Unicode input
+<kittens/unicode-input>`, etc.
+
+If you wish to support this mission and see the terminal ecosystem evolve,
+consider donating so that I can devote more time to |kitty| development.
+I have personally written `almost all kitty code
+<https://github.com/kovidgoyal/kitty/graphs/contributors>`_.
+
+You can use the `Patreon <https://www.patreon.com/kovidgoyal>`_ or `Liberapay
+<https://liberapay.com/kovidgoyal/donate>`_ services to support my kitty
+development.
