+#MediaServerUpload and MediaServerDownload are used for uploading images/files/video to
+#a remote "mediaserver" (a webserver like caddy for example).
+#When configured images/files uploaded on bridges like mattermost,slack, telegram will be downloaded
+#and uploaded again to MediaServerUpload URL
+#The MediaServerDownload will be used so that bridges without native uploading support:
+#gitter, irc and xmpp will be shown links to the files on MediaServerDownload
