+
+## Notes
+
+Thank you to all that contributed with flushing out issues and enhancements for K9s!
+I'll try to mark some of these issues as fixed. But if you don't mind grab the latest rev
+and see if we're happier with some of the fixes!
+If you've filed an issue please help me verify and close.
+
+Your support, kindness and awesome suggestions to make K9s better are, as ever, very much noted and appreciated!
+Also big thanks to all that have allocated their own time to help others on both slack and on this repo!!
+
+As you may know, K9s is not pimped out by corps with deep pockets, thus if you feel K9s is helping your Kubernetes journey,
+please consider joining our [sponsorship program](https://github.com/sponsors/derailed) and/or make some noise on social! [@kitesurfer](https://twitter.com/kitesurfer)
