-## Heed My Warning
-
-Tmuxifier is pretty much an alpha product hacked together over a weekend at
-this point. Documentation is sketchy at best, and things might drastically
-change and/or break.
-
-But if that doesn't put you off, please enjoy Tmuxifier :)

 ## Todos
 
 * Improve Readme, specially Usage section.
-* Expand `help` command with details for most commands, rather than just the
-  essential ones.
+* Write up a detailed reference for all available layout helper functions.
