-In case you are getting "No such file or directory" error for bluepy-helper, you have to go into bluepy's directory and run make there.
-It is also a good idea to let the helper have the capabilities for accessing the bluetooth devices without being root, e.g., by doing the following:
+Check that it's working correctly by running scan:
+```
+yeelightble scan -t 1
+```
+If you're getting an error you need to let the helper have the capabilities for accessing the bluetooth devices without being root by running the following:
 ```
 sudo setcap 'cap_net_raw,cap_net_admin+eip' bluepy-helper
 ```
 if you get: `Failed to set capabilities on file 'bluepy-helper' (No such file or directory)`, provide the full path to `bluepy-helper`, for example on RPI: 
 ```
 sudo setcap 'cap_net_raw,cap_net_admin+eip' /usr/local/lib/python3.7/dist-packages/bluepy/bluepy-helper
 ```
-And then simply try if the scanning works. You can use pass '-dd' as option to the command to see the debug messages from bluepy in case it is not working.
+And then try again if the scanning works.

+If you intend to use it with [homebridge-yeelight-ble](https://github.com/vsternbach/homebridge-yeelight-ble) you need to install it as a systemd service daemon, see [below](#service-daemon)
