+      Todoman is a simple, standards-based, cli todo (aka: task) manager. Todos
+      are stored into icalendar files, which means you can sync them via CalDAV
+      using, for example, vdirsyncer.
+
+      Todos are read from individual ics files from the configured directory.
+      This matches the vdir specification.  There’s support for the most common TODO
+      features for now (summary, description, location, due date and priority) for
+      now.  Runs on any Unix-like OS. It’s been tested on GNU/Linux, BSD and macOS.
+      Unsupported fields may not be shown but are never deleted or altered.
