 # Tmux Session Saver
 
-Enables saving and restoring of tmux sessions.
+Persists `tmux` environment across system restarts.
 
-Requirements / dependencies:
-- `tmux 1.9` or higher
-- `pgrep`
+Tmux is great, except when you have to restart your computer. You loose all the
+running programs, working directories, pane layouts etc.
+There are helpful management tools out there, but they require initial
+configuration and continuous updates as your workflow evolves or you start new
+projects.
+
+Enter `tmux-session-saver`: tmux persistence without configuration so there are
+no interruptions in your workflow.
+
+### About

+`tmux` environment. Here's what's been taken care of:
+
+- all sessions, windows, panes and their order
+- current working directory for each pane
+- **exact panes layout** within a window
+- active and alternative session
+- active and alternative window for each session
+- active pane for each window
+- programs running within a pane! More details in the [configuration section](#configuration).

+Requirements / dependencies: `tmux 1.9` or higher, `pgrep`

 You should now be able to use the plugin.
 
+### Configuration
+
+By default, only a conservative list of programs is restored:
+`vim emacs man less more tail top htop irssi`.
+Open a github issue if you think some other program should be on the default list.

+- Restore additional programs by putting the following in `.tmux.conf`:
+
+        set -g @session-saver-processes 'ssh telnet myprogram'
+
+- Don't restore any programs:

+- Restore **all** programs (be careful with this!):
