The previous blog post introduced the wonderful world of Visual Studio extensions. Let’s start and do some coding. During the tutorial we are going to build a VS extensions called CodyDocs and place it on [GitHub](https://github.com/michaelscodingspot/CodyDocs). CodyDocs will save code documentation in a separate file and the extension will allow to view and edit the documentation in the editor itself. In the first part, we’ll start with a simple “Hello World” program.
