 Animated-Expanding-ListView
 ===========================
 
-Animated Expanding ListView provides a fancy animation on expanding or collapsing the content of a list view item.
+Animated Expanding ListView provides a fancy animation on expanding or collapsing the content of a listview item.
 
 It works in all version of Android and it's very easy to adapt to your project.
 
+## How to use with Gradle
+
+Simply add the repository to your build.gradle file:
+```groovy
+repositories {
+	jcenter()
+	maven { url 'https://github.com/leonardocardoso/mvn-repo/raw/master/maven-deploy' }
+}
+```
+
+And you can use the artifacts like this:
+```groovy
+dependencies {
+	compile 'com.leocardz:aelv:1.1@aar'
+	// ...
+}
+```
+
+
+## Important
+<ul>
+    <li> Your list adapter must extend <b>ArrayAdapter&lt;? whatever ?&gt;</b> </li>
+    <li> Your listview item must extend from AelvListItem </li>
+        <ul>
+            <li> Right after you create your listview item, you need to call <b>yourItem.setUp(int collapsedHeight, int currentHeight, int expandedHeight, boolean isOpen);</b> to setup the dimensions.</li>
+        </ul>
+    <li> Your listview item view holder must extend from AelvListViewHolder </li>
+        <ul>
+            <li> Right after you instantiate your view holder you need to call <b>yourHolder.setViewWrap(viewWrap)</b>; and tell adapter that you are updating the item size calling <b>holder.getViewWrap().setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, listItem.getCurrentHeight()));</b>.</li>
+            <li> Right before you return the view on your custom adapter, you must call <b>yourItem.setHolder(yourHolder)</b>;</li>
+        </ul>
+    <li>You need to instantiate <b>Aelv aelv = new Aelv(isAccordion, animationDuration, yourListItems, yourListView, yourAdapter);</b> right after you setup your listview.</li>
+    <li>Last thing: your must implement <b>listview.setOnItemClickListener();</b> and insert this <b>aelv.toggle(view, position);</b> inside the listener and voilà!</li>
+</ul>
+
+Just check the app example to see it clearly.
