+## Update Local Agent
+
+If your Local Agent is outdated, you'll need to update the package manually:
+
+1. Go to the directory where you installed the local agent:
+   ```
+   $ cd /path/to/{repo-base}/local-agent
+   ```
+
+2. Fetch and rebase to get the latest commit:
+   ```
+   $ git fetch origin
+   $ git rebase origin/master
+   ```
+
+3. Enable the virtual environment and install the latest Local Agent:
+   ```
+   $ source <venv-name>/bin/activate
+   $ cd /path/to/{repo-base}/local-agent
+   $ pip install .
+   ```
+
+
 ## 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```.
 
+### The Local Agent complained that the linking code is incorrect.
+
+Make sure your local agent is talking to the correct backend service:
+The local agent will use the official backend configuration if the ```AMS_HOST```, ```AMS_PORT```
+and ```AMS_SCHEME``` are not provided in ```local_agent_config.ini```, so for the external users,
+you should just simply leave these fields blank. For the internal users who deploy the backend
+by themselves, should probably check the backend configurations in ```local_agent_config.ini```.
+
 ### My Matter device is not detected by Local Agent.
 
 Local Agent uses Pigweed RPC debug interface for communicating with Matter devices, make sure
