 This repository is a cloned and customized version of DualTachyon's open firmware found here ..
 
-https://github.com/DualTachyon/uv-k5-firmware
+https://github.com/DualTachyon/uv-k5-firmware .. a cool achievement !
 
-A cool achievement
+Use this firmware at your own risk (entirely). There is absolutely no guarantee that it will work in any way shape or form on your radio(s), it may even brick your radio(s), in which case, you'd need to buy another radio.
+Anyway, have fun.
