 # ReMux: a friendlier tmux wrapper
 
-The main point of this project is shortening commonly-used `tmux`
-commands.
-Attaching, pretty lists, and creating new sessions with group names
-are currently implemented:
+A tmux wrapper and command shortener written in Rust. ReMux's
+goal is to wrap tmux commands to be both shorter, and oriented
+around session names instead of session IDs.
 
-```bash
+In their shortest forms, *every* ReMux command is as short or
+shorter than its equivalent tmux command:
+
+```sh
 
 #	new session
 tmux new-session -t foo
