 ## Description
 
-A ohmyzsh plugin to support bookmark for directories in cmdline.
+Yet another ohmyzsh plugin to quick jump between cmdline directories.
 
-## Usage
-1. Ensure both sed & awk are already installed in you cmdline PATH.
-2. Install plugin to ohmyzsh customer plugin dir
-3. Add **bookmark** to the plugins array in your zshrc file
-    `plugins=(... bookmark)`
+And the design concern is very simple 
+
+    Add path to bookmarks, return an ordered number.
+    and use the numbers to switch between dirs finally.
 
+There are also lots of powerfull [FS Jumping](https://github.com/ohmyzsh/ohmyzsh/wiki/Plugins-Overview#fs-jumping) plugins if this is too simple for your case.
+But if you also prefer simple and intuitive solution. this plugin can also be a good alternative.
