+TODO tutorial / guide for tmux
+==============================
+
+
+## [ ] Terminologies
+
+* "session" : the entire session
+* "screen" : a separate shell / CLI / TUI program spawned by tmux and whose display is accesible from tmux.
+
+## [ ] Cheatsheet
+
+See its own cheatsheet draft.
+
+
+## [ ] Using tmux to have persistent terminal on HPC
+
+### Draft:
+
+The tmux process should be run on the login node instead of the compute node.
+Spawn as many screens as from one or more screen(s) / shell(s) within the tmux session.
+For heavier process, we should launch the "salloc" to get the shell on the compute node before running the heavy process.
