+# 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:
+
+```bash
+
+#	new session
+tmux new-session -t foo
+remux n foo
+
+#	lists
+tmux ls
+remux l
+
+#	attach
+tmux a -t foo
+remux a foo
+
+```
