 A small html/js project to nudge a user to use the desktop client for Jitsi.
 
+## Configuration
+
+All settings live in `assets/config.json`, loaded at startup. The launcher stays
+up but links break if the file is missing or malformed.
+
+| Parameter | Description |
+| --- | --- |
+| `jitsiLauncher` | Domain of this Jitsi launcher. Used for the meeting URLs created by the meeting creator (Nextcloud, adhoc link). |
+| `jitsiHost` | Jitsi domain. Used for the browser fallback URL, the desktop protocol URL and the UID of generated ICS files. |
+| `nextcloudBase` | Nextcloud instance for calendar event creation. The "Create in Nextcloud Calendar" button is only shown if this is set. |
+| `allowAdhocMeetings` | Whether adhoc meetings are allowed. The "Create Adhoc Link" button is only shown if this is `true`. |
+| `launchTimeout` | Timeout in ms before the browser fallback is shown after trying to start the jitsi-meet-electron client. |
+| `backgroundImage` | Path to the page background image. Empty: no background. |
+| `logo` | Path to the logo shown in the logo bar. Empty: logo bar stays hidden. |
+| `downloads` | Download URLs for the jitsi-meet clients, shown in the fallback view per detected OS: `windows`, `macos`, `linux`, `ios`, `android`. |
