+# Android View Helpers
+
+This library is a collection of simple view helpers to make Android development easier. Right now, this library just has a few helpful classes but they will expand over time.
+
+## SimpleAlertDialog
+
+This is a simple way to bring up a modal alert dialog within a DialogFragment within a FragmentActivity. The dialog fragment used is the `v4.support` Fragment to support all Android versions.
+
+### Usage
+
+Creating an alert to display is easy:
+
+```java
+class MyActivity extends FragmentActivity {
+	public void showDialog() {
+		SimpleAlertDialog.build(this, 
+			"Sure you want to continue?", new SimpleAlertListener() {
+				@Override
+				public void onPositive() {
+					// handle OK
+				}
+				
+				@Override
+				public void onNegative() {
+					// handle cancel
+				}
+		}
+	   ).show();
+   }
+}
+```
+
+By default, this will display the following alert:

+
+You can also adjust the alert to include no buttons, or change the button text. 
+To display just an "Sure" button:
+
+```java
+SimpleAlertDialog.build(this, 
+	"Sure you want to continue?", "Sure", null, new SimpleAlertListener()
+).show();
+```
+
+To display a "Yes" and "No" button:
+
+```java
+SimpleAlertDialog.build(this, 
+	"Sure you want to continue?", "Yes", "No", new SimpleAlertListener()
+).show();
+```
+
+You can also customize the icon in the alert and other properties:
+
+```java
+SimpleAlertDialog alert = SimpleAlertDialog.build(this, "Confirm?", new SimpleAlertListener());
+alert.setAlertIcon(R.drawable.ic_some_icon);
+alert.setAlertButtons("Yes", "No");
+alert.show();
+```
