+### Using it with your own Jitsi Meet installation
+
+In order to use this application with your own Jitsi Meet installation it's
+necessary to enable the External API. Your server must serve a `external_api.js`
+file at the root of the installation.
+
+Here is an example using nginx:
+
+```
+location /external_api.js {
+    alias /usr/share/jitsi-meet/libs/external_api.min.js;
+}
+```
+
