+Opinionated MSBuild SDKs for .NET projects with standardized build, analyzer, and editor configuration defaults:
+
+- `Geekeey.Arcade.NET.Sdk` — base SDK
+- `Geekeey.Arcade.NET.Sdk.Web` — ASP.NET Core web projects
+- `Geekeey.Arcade.NET.Sdk.Test` — test projects
+
+## Packaging metadata
+
+Set these properties in your project file or a directory-level props file. Unless stated otherwise, defaults apply only when the property is empty.
+
+| Property | Default | Description |
+| --- | --- | --- |
+| `Authors` | `The Geekeey Team` | Default authors when no value is set. |
+| `Copyright` | `Copyright (c) The Geekeey Team` | Default copyright when no value is set. |
+| `PublishRepositoryUrl` | `true` | Publishes the repository URL in packages. |
+| `IncludeSymbols` | `true` | Packs a symbol package. |
+| `SymbolPackageFormat` | `snupkg` | Format of the symbol package. |
+| `PackageReadmeFile` | `README.md` when found | Packs a README file from the project directory as the package readme. |
+| `SearchReadmeFileAbove` | `false` | When `true`, searches parent directories for a README to pack. |
+| `PackageLicenseFile` | Detected license file | Packs and declares a `LICENSE.txt`, `LICENSE.md` or `LICENSE` file found in the project directory or a parent directory. Skipped when the project sets `PackageLicenseExpression` or `PackageLicenseFile`. |
