+# Avalonia Stack
+
+This repository can be used as a `dotnet new` project template. The template
+replaces the `Avalonia` prefix in solution files, project files, folder names,
+project references, C# namespaces, packaging scripts, and frontend names when a
+new project is created.
+
+Use a C# namespace friendly project name such as `DemoApp` or `QiChengApp`.
+Avoid names with `-`, spaces, or a leading digit because the generated name is
+also used inside C# namespaces.
+
+## Generate from a local clone
+
+```powershell
+dotnet new install .
+dotnet new Qiang-avalonia-stack -n DemoApp -o ..\DemoApp
+```
+
+The generated solution entry point is `DemoApp-Stack.slnx`. Project folders,
+project files, and generated C# namespaces keep the project name casing from
+`-n`.
+
+## Build an installable template package
+
+```powershell
+dotnet pack .\Avalonia.Stack.TemplatePack.csproj -c Release
+dotnet new install .\bin\Release\QiCheng.Avalonia.Stack.Templates.1.0.0.nupkg
+dotnet new Qiang-avalonia-stack -n DemoApp -o .\DemoApp
+```
+
+Publish the generated `.nupkg` to a private or public NuGet feed when you want
+to create named projects without cloning this template repository first.
