-## tmux sessionizer
+# tmux sessionizer
 its a script that does everything awesome at all times
 
-## Usage
+## Basic usage
 ```bash
 tmux-sessionizer [<partial name of session>]
 ```
 
+By default, tmux-sessionizer holds its state in .tmux-sessionizer.txt in your
+$HOME directory, but this can be changed within the top of tmux-sessionizer
+itself
+
+## Options
+    -a, -add
+        Adds full filepaths to your tmux-sessionizer list via stdin or
+        interactive mode. It will automatically reject duplicates, and will
+        only accept valid absolute filepaths to folders that exist.
+
+    -d, -delete
+        Opens a multi-select fzf of your current tmux-sessionizer list which
+        can be used to delete files in your list by selecting either one file
+        to delete using the enter key, or multiple files using tab to select
+        multiple files and then enter to delete those files. CTRL-C to exit
+
+    -l, -list
+        Lists the contents of the tmux-sessionizer list.
+
+### Example commands
+Add all directories within the current working directory to your list.
+```bash
+find $(pwd) -maxdepth 1 -type d | tmux-sessionizer -a
+```
+
+Enter fzf and delete folders in your tmux-sessionizer list by selecting them
+with tab and then clicking enter
+```bash
+tmux-sessionizer -d
+```
+
+List all the directories in your tmux-sessionizer list
+```bash
+tmux-sessionizer -l
+```
+
 if you execute tmux-sessionizer without any parameters it will assume FZF and
 try to fuzzy find over a set of directories.

-TODO: waiting on that directory list to be dynamic :) (go a head make pr if you want)
