 ### A2.1 Pairing Command Failed
 
 I cannot finish the commissioning on the controller example:
 
--   Currently this example only supports onnetwork pairing, so please make sure that the end-device and the controller are on the same IP-network.
+-   For onnetwork pairing, please make sure that the end-device and the controller are on the same IP-network.
 -   The controller uses the hard-code test PAA certification so the PAI and DAC on the end-device should be generated by the [test cert](https://github.com/espressif/connectedhomeip/blob/4f7669b052b16bd054227376e1bbadac85419793/credentials/test/attestation/Chip-Test-PAA-NoVID-Cert.pem) and the [test key](https://github.com/espressif/connectedhomeip/blob/4f7669b052b16bd054227376e1bbadac85419793/credentials/test/attestation/Chip-Test-PAA-NoVID-Key.pem)
 -   If you are still facing issues, reproduce the issue on the default example for the device and then raise an [issue](https://github.com/espressif/esp-matter/issues). Make sure to share these:
