An average guy's IT (mis)adventures

Here's how you add an F-Droid XMPP App to "mod_register_apps.lua" so that it shows up in the Invite registration page of prosody:

        {
                name = "monocles chat";
                text = [[monocles chat is a fork of blabber.im and Conversations with some changes, to improve usability.]];
                image = "assets/logos/monocles.png";
                link = "https://f-droid.org/packages/de.monocles.chat/";
                platforms = { "Android" };
                supports_preauth_uri = true;
                download = {
                        buttons = {
                                {
                                        image = "https://woodpeckersnest.space/images/fdroid.png";
                                        url = "https://f-droid.org/packages/de.monocles.chat/";
                                };
                        };
                };
        };

Add the "monocles.png" logo to your "assets/logos/" directory and change the "fdroid.png" image link accordingly.
