+A set of tmux options that should be acceptable to everyone.
 
 Inspired by [vim-sensible](https://github.com/tpope/vim-sensible).
 
 ### Principles
 
 - `tmux-sensible` options should be acceptable to **every** tmux user!<br/>
-  If any option bothers you, please open an issue and it will probably be
-  updated (or removed).
+  If any of the options bothers you, please open an issue and it will probably

 - if you think a new option should be added, feel free to open a pull request.
 - **no overriding** of user defined settings.<br/>
   Your existing `.tmux.conf` settings are respected and they won't be changed.

     bind C-n next-window
 
+Above bindings enhance the default `prefix + p` and `prefix + n` bindings by

+`C-a`), which is a lot quicker.

+### Almost sensible options - deprecated
+
+**Note**: this feature is deprecated and will be removed from `tmux-sensible`
+in the next major release. The reason for this is to focus this plugin on doing
+just one thing (and hopefully doing it well).<br/>
+If you were using 'almost sensible' the path forward is to move all the
+below options to your `.tmux.conf`.
+
+Activate these by putting `set -g @almost-sensible 'on'` in `.tmux.conf`.

 ### Installation with [Tmux Plugin Manager](https://github.com/tmux-plugins/tpm) (recommended)
 
 Add plugin to the list of TPM plugins in `.tmux.conf`:
 
-    set -g @tpm_plugins "             \
+    set -g @tpm_plugins '             \

       tmux-plugins/tmux-sensible      \
-    "
+    '
 
 Hit `prefix + I` to fetch the plugin and source it. That's it!
