+### Global Library Installation
+
+Some javascript libraries need to be added to the global scope, and loaded as if 
+they were in a script tag. We can do this using the `apps[0].scripts` and 
+`apps[0].styles` properties of `angular-cli.json`.
+
+As an example, to use [Boostrap 4](http://v4-alpha.getbootstrap.com/) this is 
+what you need to do:
+
+First install Bootstrap from `npm`:
+
+```bash
+npm install bootstrap@next
+```
+
+Then add the needed script files to to `apps[0].scripts`.
+
+```
+"scripts": [
+  "../node_modules/jquery/dist/jquery.js",
+  "../node_modules/tether/dist/js/tether.js",
+  "../node_modules/bootstrap/dist/js/bootstrap.js"
+],
+```
+
+Finally add the Bootstrap CSS to the `apps[0].styles` array:
+```
+"styles": [
+  "styles.css",
+  "../node_modules/bootstrap/dist/css/bootstrap.css"
+],
+```
+
+Restart `ng serve` if you're running it, and Bootstrap 4 should be working on 
+your app.
+
 ### Updating angular-cli
 
 To update `angular-cli` to a new version, you must update both the global package and your project's local package.
