+# Arcade Build System
+
+This repository uses the [dotnet/arcade](https://github.com/dotnet/arcade) build system for versioning, signing, packaging, publishing, and CI/CD.
+
+## Key Files
+
+| File | Purpose |
+|------|---------|
+| `global.json` | Pins Arcade SDK version |
+| `Directory.Build.props` | Imports Arcade Sdk.props, sets common properties |
+| `Directory.Build.targets` | Imports Arcade Sdk.targets |
+| `eng/Versions.props` | Version prefix, pre-release label, all dependency versions |
+| `eng/Version.Details.xml` | Tracks dependency source repos and SHAs for maestro |
+| `eng/Publishing.props` | Publishing configuration (V3) |
+| `eng/common/` | Shared arcade build scripts (do not edit manually) |
+| `Directory.Packages.props` | Central Package Management — versions reference `eng/Versions.props` properties |
+
+## Versioning
+
+Arcade manages versions automatically:
+- **VersionPrefix**: `0.1.0` (from `eng/Versions.props`)
+- **PreReleaseVersionLabel**: `preview`
+- Official builds append build number: `0.1.0-preview.26166.3`
+
+## Building
+
+```bash
+# Local build
+dotnet build
+
+# CI-style build (uses arcade scripts)
+./eng/common/cibuild.sh --configuration Release --prepareMachine
+```
+
+## Shipping Packages
+
+All DevFlow library packages have `IsShipping=true` and will be published to NuGet feeds:
+- Microsoft.Maui.DevFlow.Agent
+- Microsoft.Maui.DevFlow.Agent.Core
+- Microsoft.Maui.DevFlow.Agent.Gtk
+- Microsoft.Maui.DevFlow.Blazor
+- Microsoft.Maui.DevFlow.Blazor.Gtk
+- Microsoft.Maui.DevFlow.CLI
+- Microsoft.Maui.DevFlow.Driver
+- Microsoft.Maui.DevFlow.Logging
+
+## Dependency Flow
+
+Dependencies are tracked in `eng/Version.Details.xml` and updated automatically by maestro via darc subscriptions. See the PR description for setup commands.
+
+## Updating eng/common/
+
+The `eng/common/` directory is managed by arcade and updated automatically via darc. Do not edit files in this directory manually.
