 .SH DESCRIPTION
 .B mcol
 is a terminal browser for a directory of release lists.
-It reads two-part paths as artist/album and longer paths as
-label/artist/release.
+The directory must contain an
+.I all.txt
+catalog.  Each non-empty line is a slash-separated release path.  Two-part
+paths are interpreted as artist/album; paths with three or more parts are
+interpreted as label/artist/release, with any remaining parts retained in the
+release name.  Parent paths are not counted as releases.
 .PP
 The input directory comes from
 .BR \-\-input ,

-All recognized files are scanned.

+# Demo
+
+Run this small set of release lists from the repository root:
+
+```sh
+make tui INPUT=demo
+```
+
+The dated lists demonstrate daily, legacy, session, and weekly activity
+sources. mcol derives its browsable release library from these files.
