+### Creating a test device
+
+Instruction on how to create a test device can be found [here](https://nabucasa.github.io/matter-example-apps/).
+
+### Commissioning a test device
+
+Currently the easiest way to set up a test device is using the Python CHIP REPL. Start it by pointing it at the same storage location as the servier will run off:
+
+```
+sudo chip-repl --storagepath=$HOME/.chip-storage/python-kv.json
+```
+
+Inside the Python REPL, configure your Wi-Fi credentials:
+
+```python
+devCtrl.SetWiFiCredentials("SSID", "PW")
+```
+
+Once done, paste the following code to commission the device:
+
+```python
+from chip.setup_payload import SetupPayload
+setupPayload = SetupPayload().ParseQrCode("MT:Y.K9042C00KA0648G00")
+import ctypes
+longDiscriminator = ctypes.c_uint16(int(setupPayload.attributes['Discriminator']))
+pincode = ctypes.c_uint32(int(setupPayload.attributes['SetUpPINCode']))
+
+devCtrl.ConnectBLE(longDiscriminator, pincode, 4335)
+```
+
+If you have installed the lighting app, send the following command to test if it works:
+
+```python
+await devCtrl.SendCommand(4335, 1, Clusters.OnOff.Commands.Toggle())
+```
