 ## Example of usage
 
-A simple example of usage is in the [main.py](https://github.com/pycom/pycom-libraries/blob/master/lib/pymesh/main.py).
+A simple example of usage can be found [here](/pymesh/simple-example/).
 
 ## Specifications
 
-It can be easily customised, by modifying any file from [/lib folder](https://github.com/pycom/pycom-libraries/tree/master/pymesh/lib/) and flashing it to the board. The uploaded file will automatically be executed instead of the _frozen_ one, which is already embedded into the binary firmware.

-This code reads PIR sensor triggers from this simple [PIR sensor](https://www.kiwi-electronics.nl/PIR-Motion-Sensor) and sends an HTTP request for every trigger, in this case to a [Domoticz](https://domoticz.com/) installation. When motion is constantly detected, this PIR sensor keeps the pin high, in which case this code will keep sending HTTP requests every 10 seconds (configurable with the hold\_time variable).
