+## Overview
+
+A cross platform application that shows repository and user data from GitHub, built with Avalonia.
+
+So, I finally done it.
+
+I have built a [project](https://scm.wyattjmiller.com/wymiller/DeskHubSharp) in the past that achieves the same goals as this application (albeit unmaintained), but this project is much, much different. I took the original program, ripped out the WPF bits, and stored all the Avalonia bits where the WPF bits used to be, with a few additions. While this project is going to serve a great portion of what the original project did, there are a few adjustments, and perhaps a few additions. 
+
+I also ripped out the legacy .NET Framework and put .NET 6 in it's place, which brings many [improvements](https://docs.microsoft.com/en-us/dotnet/core/whats-new/dotnet-6).
+
+###### What is Avalonia?
+
+Think WPF but cross platform. Avalonia still runs your favorite declarative language, XAML, but applies a different drawing library, Skia (SkiaSharp). What Skia allows Avalonia to do is draw windows, buttons, and other widgets on not just Windows, but macOS, Linux, Android, and iOS. Even Web Assembly! Learn more [here](http://avaloniaui.net/).
