+# Docker-Based CTX
+
+CTX can be run in a Docker container, providing a consistent environment across different platforms and simplifying
+deployment. This guide covers how to configure and use CTX in a Docker container, including integration with Claude's
+MCP server.
+
+## Benefits of Docker-Based Deployment
+
+- **Cross-platform consistency**: Same behavior regardless of host OS
+- **Simplified deployment**: No need to install dependencies on host systems
+- **Multi-architecture support**: Works on both amd64 and arm64 architectures
+- **CI/CD integration**: Easy to incorporate into pipeline workflows
+- **Isolated environments**: Run different CTX versions side-by-side
+- **Container orchestration**: Integrates with Kubernetes, Docker Swarm, etc.
+
+## Using the Docker Image
+
+### Pull the Docker Image
+
+```bash
+docker pull ghcr.io/context-hub/ctx:latest
+```
+
+### Run CTX Commands in Docker
+
+To run CTX commands in Docker, you need to mount your project directory as a volume:
+
+```bash
+docker run --rm -v /path/to/your/project:/workspace ghcr.io/context-hub/ctx:latest <command> <options>
+```
+
+For example, to generate context in the current directory:
+
+```bash
+docker run --rm -v $(pwd):/workspace ghcr.io/context-hub/ctx:latest generate
+```
+
+## Integrating with Claude's MCP Server
+
+To configure Claude's desktop app to use CTX in a Docker container as an MCP server, you'll need to modify the Claude
+desktop configuration.
+
+```json
+{
+  "mcpServers": {
+    "ctx": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "-v",
+        "/path/to/project:/workspace",
+        "ghcr.io/context-hub/ctx:latest",
+        "server",
+        "-c",
+        "/workspace"
+      ]
+    }
+  }
+}
+```
+
+#### Windows with WSL Configuration
+
+```json
+{
+  "mcpServers": {
+    "ctx": {
+      "command": "bash.exe",
+      "args": [
+        "-c",
+        "docker run --rm -i -v /path/to/project:/workspace ghcr.io/context-hub/ctx:latest server -c /workspace"
+      ]
+    }
+  }
+}
+```
+
+## Docker Compose Example
+
+For more complex setups, you can use Docker Compose to manage your CTX deployment:
+
+```yaml
+# docker-compose.yml
+version: '3'
+services:
+  ctx:
+    image: ghcr.io/context-hub/ctx:latest
+    volumes:
+      - ./:/workspace
+    environment:
+      - GITHUB_PAT=${GITHUB_PAT}
+      - MCP_FILE_OPERATIONS=true
+    command: server -c /workspace
+```
