-Pick your OS below. Each section is self-contained: install Docker, get the project, start it.
+> [!WARNING]
+> **Do not use Docker Desktop for a normal Windows deployment.** Linux
+> containers on Windows run through a WSL2/Hyper-V virtual machine. This is
+> substantially slower than running Overlord directly on Windows or on a
+> Linux host, and the extra virtualization/networking layer provides fewer
+> host-integration features.
+
+For the best experience, choose one of these:
+
+1. **Linux host:** run the provided Docker Compose deployment (recommended),
+   or use the native Linux scripts.
+2. **Windows host:** run Overlord directly on Windows using the
+   [native/bare-metal scripts](#native-bare-metal-installation).
+
+The Windows Docker Compose file remains available for compatibility and
+testing, but it is not the recommended Windows installation method.

+## Docker Quick Start (Recommended on Linux)
+
+Docker is recommended on a Linux host. The macOS and Windows instructions are
+provided for compatibility and local testing; Windows users should prefer a
+native installation or move the server to Linux.
 
 > Windows and macOS use `docker-compose.windows.yml`. Linux uses the default `docker-compose.yml` (host networking).
