 Trusting Embassy CA on Linux
 ============================
 
-Nothing specific needs to be configured for the Linux environment.
+Nothing specific needs to be configured for the Linux environment at an OS level if you are only connecting over LAN through a **browser**.
+
+However, if you want to connect over LAN using a **native app** (e.g. the Bitwarden app or ``git``) you will need to trust the Root CA.
+
+Trusting Embassy CA on Ubuntu / Debian
+--------------------------------------
+
+From the folder you have downloaded your Embassy’s Root CA, run the following commands:
+
+    .. code-block:: bash
+
+        sudo apt-get install -y ca-certificates
+        sudo cp Embassy\ Local\ CA.crt /usr/local/share/ca-certificates
+        sudo update-ca-certificates
+
+
+In the output it should say ``1 added`` if it was successful.
