+Windows installation with Docker
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Windows users should run VulnerableCode with Docker Desktop. Native Windows
+installation is not supported.
+
+Install and start Docker Desktop, then open PowerShell and clone the repository::
+
+    git clone https://github.com/aboutcode-org/vulnerablecode.git
+    cd vulnerablecode
+
+Create the configuration directory and an environment file using PowerShell.
+Replace the example values below with your own strong, unique secrets. Do not
+use the example values as-is::
+
+    New-Item -ItemType Directory -Force .\vulnerablecode-config
+    @"
+    SECRET_KEY=replace-with-a-strong-random-secret
+    ALTCHA_HMAC_KEY=replace-with-a-32-byte-hex-value
+    "@ | Set-Content .\vulnerablecode-config\.env
+
+The repository includes ``docker-compose.windows.yml`` to mount this configuration
+directory into the application, scheduler, and RQ worker containers. Start and
+check the services with::
+
+    docker compose -f docker-compose.yml -f docker-compose.windows.yml up -d
+    docker compose -f docker-compose.yml -f docker-compose.windows.yml ps
+
+VulnerableCode should then be available at::
+
+    http://localhost
+
+To stop the services::
+
+    docker compose -f docker-compose.yml -f docker-compose.windows.yml down
