-## Docker
+## Container Images
 
-### Building the Docker Image
+### Registry
+
+Official images are published to Quay.io:
+
+```
+quay.io/stackrox-io/mcp
+```
+
+### Supported Architectures
+
+Multi-architecture images support the following platforms:
+
+- `linux/amd64` - Standard x86_64 architecture
+- `linux/arm64` - ARM 64-bit (Apple Silicon, AWS Graviton, etc.)
+- `linux/ppc64le` - IBM POWER architecture
+- `linux/s390x` - IBM Z mainframe architecture
+
+Docker/Podman will automatically pull the correct image for your platform.
+
+### Available Tags
+
+| Tag Pattern | Description | Example |
+|-------------|-------------|---------|
+| `latest` | Latest release version | `quay.io/stackrox-io/mcp:latest` |
+| `v{version}` | Specific release version | `quay.io/stackrox-io/mcp:v1.0.0` |
+| `{commit-sha}` | Specific commit from main branch | `quay.io/stackrox-io/mcp:a1b2c3d` |
+
+### Usage
+
+#### Pull Image
 
-Build the image locally:
 ```bash
-VERSION=dev make image
+docker pull quay.io/stackrox-io/mcp:latest
+# or
+podman pull quay.io/stackrox-io/mcp:latest
 ```
 
-### Running the Container
+#### Run Container
 
-Run with default settings:
 ```bash
-docker run --publish 8080:8080  --env STACKROX_MCP__TOOLS__CONFIG_MANAGER__ENABLED=true --env STACKROX_MCP__CENTRAL__URL=<central host:port> quay.io/stackrox-io/stackrox-mcp:dev
+docker run -p 8080:8080 \
+  --env STACKROX_MCP__CENTRAL__URL=central.stackrox:443 \
+  --env STACKROX_MCP__TOOLS__CONFIG_MANAGER__ENABLED=true \
+  quay.io/stackrox-io/mcp:latest
+```
+
+### Building Images Locally
+
+Build a single-platform image:
+```bash
+VERSION=dev make image
 ```
