 A custom WordPress nav walker class to fully implement the Bootstrap 3.0+ navigation style in a custom theme using the WordPress built in menu manager.
 
-## Bootstrap 2.x vs Bootstrap 3.0
-
-There are many changes Bootstrap 2.x & Bootstrap 3.0 that affect both how the nav walker class is used and what the walker supports. For CSS changes I recommend reading the [Migrating from 2.x to 3.0](https://getbootstrap.com/getting-started/#migration) in the official Bootstrap docs.
-
-The most noticeable functionality change in Bootstrap 3.0.0+ is that it only supports a single dropdown level. This script is intended to implement the Bootstrap 3.0 menu structure without adding additional features, so additional dropdown levels will not be supported.
-
-If you would like to use **Bootstrap 2.x** you can use the [legacy version](https://github.com/twittem/wp-bootstrap-navwalker/tree/For-Bootstrap-2.3.2) of the walker class.

 ## NOTE
 
 This is a utility class that is intended to format your WordPress theme menu with the correct syntax and classes to utilize the Bootstrap dropdown navigation, and does not include the required Bootstrap JS files. You will have to include them manually.
