 # Details
+
+To use `choose`, you need a directory structure
+
+Given a `CHOOSE_DB_DIR` variable of `~/db`, layout a structure like the following
+
+```txt
+db
+ - <category-name-1>
+   - <application-name-1>
+     - launch.sh
+   - <application-name-2>
+     - launch.sh
+```
+
+For example...
+
+```txt
+db
+ - window-manager/
+   - _.current
+   - awesome/
+     - launch.sh
+   - i3/
+     - launch.sh
+ - menu-bar/
+   - _.current
+   - lemonbar/
+     - launch.sh
+   - xmobar/
+     - launch.sh
+```
