 ```
 
+
+## Troubleshooting
+
+### I can't install the Local Agent on my host.
+
+Make sure you're using Ubuntu LTS on your host and python version is ```>= 3.7```.
+
+### My Matter device is not detected by Local Agent.
+
+Local Agent uses Pigweed RPC debug interface for communicating with Matter devices, make sure
+your Matter device implements the Pigweed RPC endpoint and your Matter device class is already
+registered in GDM (step 5 in the ```Setup``` section). You can also try detecting the devices
+via GDM directly by following the [GDM instructions](https://github.com/google/gazoo-device#detecting-devices).
+
+### What if my Matter device is accidentally shutdown during the test execution?
+
+If the device gets shutdown or rebooted during test execution, GDM may crash and you'll need to close
+the Local Agent and restart it again after the test execution. Local agent does not need to be re-linked..
+
+### What if my host machine is accidentally shutdown during the test execution?
+
+Local agent will be closed forcely and you'll need to restart it. Local agent does not need to be re-linked.
