+## What's included?
+
+I wanted to keep this library really small and just created it for myself, but I hope others find it useful. Here is what I added in and feel free to request new things in the Issues tab.
+
+### ObservableObject
+Simple implementation of INotifyPropertyChanged that any class can inherit from.
+
+```csharp
+/// <summary>
+/// Sets the property.
+/// </summary>
+/// <returns><c>true</c>, if property was set, <c>false</c> otherwise.</returns>
+/// <param name="backingStore">Backing store.</param>
+/// <param name="value">Value.</param>
+/// <param name="propertyName">Property name.</param>
+/// <param name="onChanged">On changed.</param>
+/// <typeparam name="T">The 1st type parameter.</typeparam>
+protected bool SetProperty<T>( ref T backingStore, T value,
+    [CallerMemberName]string propertyName = "",
+    Action onChanged = null)
+```
+
+```csharp
+// <summary>
+/// Raises the property changed event.
+/// </summary>
+/// <param name="propertyName">Property name.</param>
+protected void OnPropertyChanged([CallerMemberName]string propertyName = "")
+```
+
+### BaseViewModel
+Your base view model! It implements INotifyPropertyChanged and a bunch of default properties such as **Title, SubTitle, Icon, IsBusy, IsNotBusy, CanLoadMore**.
+
+### Grouping
+Best way to group items into a Key/Value pair ObservableCollection for managing groups of data. See my blog post: motzcod.es/post/94643411707/enhancing-xamarinforms-listview-with-grouping
+
+### ObservableRangeCollection
+A super awesome ObservableCollection that adds important methods such as: **AddRange, RemoveRange, Replace, and ReplaceRange**.
+
+### Utils
+Any and all extension methods that are nifty. Here are the current ones:
+
+```csharp
+/// <summary>
+/// Task extension to add a timeout.
+/// </summary>
+/// <returns>The timeout.</returns>
+/// <param name="task">Task.</param>
+/// <param name="duration">Duration.</param>
+/// <typeparam name="T">The 1st type parameter.</typeparam>
+public async static Task<T> WithTimeout<T>(this Task<T> task, int duration)
+```
