       an SVG.
    1. `url`: An HTTP URL for where to send the user to download the desktop build.
+1. `mobileBuilds`: Used to alter promotional links to the mobile app. By default the
+   builds are considered available and accessible from https://element.io. This config
+   option is typically used in a context of encouraging the user to try the mobile app
+   instead of a mobile/incompatible browser. There are 3 possible fields for this config
+   option: `ios`, `android`, `fdroid`. For all 3, when set to a string then that URL will
+   be used. When not defined, the default element.io apps will be used. When explicitly
+   set to `null`, that platform will be considered unavailable.
 1. `mobileGuideToast`: Whether to show a toast a startup which nudges users on
    iOS and Android towards the native mobile apps. The toast redirects to the
    mobile guide if they accept. Defaults to false.
