+# Ladda for Bootstrap 3
+
+Buttons with built-in loading indicators, effectively bridging the gap between action and feedback. 
+
+[Check out the demo page](http://msurguy.github.io/ladda-bootstrap/).
+
+## Instructions
+
+Please see the demo page for the details: (http://msurguy.github.io/ladda-bootstrap/).
+
+#### HTML
+
+Ladda buttons must be given the class ```ladda-button``` and the button label needs to have the ```ladda-label``` class. The ```ladda-label``` will be automatically created if it does not exist in the DOM. Below is an example of a button which will use the expand-right animation style.
+
+```html
+<button class="ladda-button" data-style="expand-right"><span class="ladda-label">Submit</span></button>
+```
+
+Buttons accepts three attributes:
+- **data-style**: one of the button styles, full list in [demo](http://lab.hakim.se/ladda/) *[required]*
+- **data-color**: green/red/blue/purple/mint
+- **data-size**: xs/s/l/xl, defaults to medium
+- **data-spinner-size**: 40, pixel dimensions of spinner, defaults to dynamic size based on the button height
+- **data-spinner-color**: A hex code or any [named CSS color](http://css-tricks.com/snippets/css/named-colors-and-hex-equivalents/). 
+
+#### JavaScript
+
+If you will be using the loading animation for a form that is submitted to the server (always resulting in a page reload) you can use the ```bind()``` method:
+
+```javascript
+// Automatically trigger the loading animation on click
+Ladda.bind( 'input[type=submit]' );
+
+// Same as the above but automatically stops after two seconds
+Ladda.bind( 'input[type=submit]', { timeout: 2000 } );
+```
+
+If you want JavaScript control over your buttons you can use the following approach:
+
+```javascript
+// Create a new instance of ladda for the specified button
+var l = Ladda.create( document.querySelector( '.my-button' ) );
+
+// Start loading
+l.start();
+
+// Will display a progress bar for 50% of the button width
+l.setProgress( 0.5 );
+
+// Stop loading
+l.stop();
+
+// Toggle between loading/not loading states
+l.toggle();
+
+// Check the current state
+l.isLoading();
+```
+
+All loading animations on the page can be stopped by using:
+
+```javascript
+Ladda.stopAll();
+```
+
