-**Building ripple-lib from github**
+**Building ripple-lib for browser environments**
+
+ripple-lib uses Gulp to generate browser builds. These steps will generate minified and non-minified builds of ripple-lib in the `build/` directory.
 
 ```
   $ git clone https://github.com/ripple/ripple-lib
   $ npm install
   $ npm run build
 ```
 
-Then use the minified `build/ripple-*-min.js`
+**Restricted browser builds**
