+### Note
+Please dont ask too add devices where you cant provide a basic working configuration (other than sonoff). Since there are thousands of them..
+
 ### Quick Install
 Download one of the released binaries from https://github.com/arendst/Sonoff-Tasmota/releases and flash it to your hardware as documented in the wiki.
