+### Customize templates
+
+As mentioned directives from this repository have all the markup externalized in templates. You might want to customize default
+templates to match your desired look & feel, add new functionality etc.
+
+The easiest way to override an individual template is to use the <script> directive:
+
+```javascript
+<script id="template/alert/alert.html" type="text/ng-template">
+    <div class='alert' ng-class='type && "alert-" + type'>
+        <button ng-show='closeable' type='button' class='close' ng-click='close()'>Close</button>
+        <div ng-transclude></div>
+    </div>
+</script>
+```
+
+If you want to override more templates it makes sense to store them as individual files and feed the `$templateCache` from those partials.
+For people using Grunt as the build tool it can be easily done using the `grunt-html2js` plugin. You can also configure your own template url.
+Let's have a look:
+
+Your own template url is `views/partials/ui-bootstrap-tpls/alert/alert.html`.
+
+Add "html2js" task to your Gruntfile
+```
+html2js: {
+  options: {
+    base: '.',
+    module: 'ui-templates',
+    rename: function (modulePath) {
+      var moduleName = modulePath.replace('app/views/partials/ui-bootstrap-tpls/', '').replace('.html', '');
+      return 'template' + '/' + moduleName + '.html';
+    }
+  },
+  main: {
+    src: ['app/views/partials/ui-bootstrap-tpls/**/*.html'],
+    dest: '.tmp/ui-templates.js'
+  }
+}
+```
+
+Make sure to load your template.js file
+`<script src="/ui-templates.js"></script>`
+
+Inject the `ui-templates` module in your `app.js`
+```
+angular.module('myApp', [
+  'ui.bootstrap',
+  'ui-templates'
+]);
+```
+
+Then it will work fine!
