 # Control I/O pins with a webhook
 
 This is an Arduino IDE sketch for a "smart" controller that can activate pins
-based on the state of some webpage. The motivating use cases are:
+based on the state of some webpage. (designed to be driven by [gpio webhook server](https://git.annabunch.es/annabunches/gpio-webhook-server))
+The motivating use cases are:
 
 * Controlling a PC power switch remotely, using a transistor wired to the power switch pins
 * Lighting specific LEDs to create a remotely controlled 'traffic light'.
 
 This sketch currently targets only the ESP8266, and will probably not work with other
-microcontrollers. Support for other boards may come if I run out of ESP8266's.
