+### Wine And Proton
+- **Standard controls**: Focus, name, value, role, state, and selection changes from MSAA controls
+- **Unmodified clients**: Implements the NVDA Controller RPC endpoint used by the official controller DLLs
+- **Tolk compatibility**: Provides the NVDA detection window expected by the official `Tolk.dll`
+- **Prefix management**: Runs one helper per active same-user Wine or Proton prefix and preserves Proton's loader
+
+The built-in Wine Accessibility plugin is enabled by default when the helper is installed. Its
+preferences page controls automatic prefix management, standard-control reading, and controller
+compatibility independently. Custom-drawn game interfaces are not made accessible by this bridge.
+See [Wine accessibility](docs/wine-accessibility.md) for build and protocol details.
