+Unofficial WiringPi Mirror
+==========================
+
+This is an unofficial mirror of WiringPi to support ports (Python/Ruby/etc).  With the
+[end of official development](http://wiringpi.com/wiringpi-deprecated/), this repository
+has become a mirror of the last "official" source release as well as a source for small
+updates to support newer hardware (primarily for use by the ports).
+
+  * The final "official" source release can be found at the
+    [`final_source_2.50`](https://github.com/WiringPi/WiringPi/tree/final_official_2.50) tag.
+  * The default `master` branch contains code that has been written since that final source
+    release to provide support for newer hardware.
+
+Please do not email Gordon if you have issues, he will not be able to help.
+
+Pull-requests may be accepted to add or fix support for newer hardware, but new features or
+other changes will not be accepted.
+
+For support, comments, questions, etc please join the WiringPi Discord channel: https://discord.gg/SM4WUVG
