+Initialize an empty folder for a new project by copying and modifying files from our [repository-template](https://github.com/SpatialFocus/repository-template). This includes:
+
+- .gitignore and .editorconfig
+- stylecop.json and ReSharper settings
+- MSBuild properties
+- Solution file including the default _Solution Items_ solution folder
+- README.md
+
+Placeholders in these files will be filled with solution name and author information.
+
+Additionally, the wizard supports the creation of .NET Core projects in the solution. Currently, these project templates are available:
+
+1) Console app
+2) Empty web
+3) Web API
+4) Web MVC
+5) Xamarin Forms Shell (using our [Xamarin Forms Shell template](https://github.com/SpatialFocus/DotNetNew.XamarinFormsShell))
+6) Blazor Server
+7) Blazor Wasm
+
+After setting up one of these demo projects, typical generic projects can be added as well:
+
+- Business (class library for business logic)
+- Shared (class library for shared data)
+- Test (nunit test project)
+
