+"""`MSU MFSD`_ is a database for face PAD experiments.
+
+Database created at MSU, for face-PAD experiments. The public version of the database (available here) contains
+280 videos corresponding to 35 clients. The videos are grouped as 'genuine' and 'attack'.
+The attack videos have been constructed from the genuine ones,
+and consist of three kinds: print, iPad (video-replay), and iPhone (video-replay).
+Face-locations are also provided for each frame of each video, but some (6 videos) face-locations are not reliable,
+because the videos are not correctly oriented.
+The reference citation is [XXX]_.
+
+You can download the raw data of the `MSU MFSD`_ database by following
+the link.
