+## SimpleProgressDialog
+
+Often in an application there might be a long running task that requires the UI to be blocked 
+such as uploading an image. While this isn't the best UI, occassionally this can come up.

+
+```java
+SimpleProgressDialog dialog = SimpleProgressDialog.build(this);
+```
+
+By default, this will display the following alert:

+
+You can dismiss the dialog once the task is complete with:
+
+```java
+dialog.dismiss();
+```
+
+You can also adjust the progress dialog to have a custom message:
+
+```java
+SimpleProgressDialog dialog = SimpleProgressDialog.build(this, "Uploading...");
+dialog.show();
 ```
