+      OpenLP is a free church presentation software.
+
+      Features:
+
+      * Cross platform between Linux, Windows, OS X and FreeBSD
+      * Display songs, Bible verses, presentations, images, audio and video
+      * Control OpenLP remotely via the Android remote, iOS remote or mobile web browser
+      * Quickly and easily import songs from other popular presentation packages
+      * Easy enough to use to get up and running in less than 10 minutes
+
+      Remark: This pkg only supports sqlite dbs. If you wish to have support for
+            mysql or postgresql dbs, or Jenkins, please contact the maintainer.
+
+      Bugs which affect this software packaged in Nixpkgs:
+
+      1. The package must disable checks, because they are lacking the qt env.
+         (see pkg source and https://discourse.nixos.org/t/qt-plugin-path-unset-in-test-phase/)
+      2. There is a segfault on exit. Not a real problem, according to debug log, everything
+         shuts down correctly. Maybe related to https://forums.openlp.org/discussion/3620/crash-on-exit.
+         Plan: Wait for OpenLP-3, since it is already in beta 1
+         (2021-02-09; news: https://openlp.org/blog/).
