+#### Option 1: Using Docker Compose (Recommended)
+
+This is the recommended method for running MemMachine locally using Docker. It's the easiest way to get started.
+
+**Step 1: Start MemMachine with Docker Compose**
+
+First, start MemMachine using the provided script:
+
+```
+./memmachine-compose.sh
+```
+
+This will start all required services (PostgreSQL, Neo4j, and MemMachine) in Docker containers. The MemMachine container will be named `memmachine-app`.
+
+**Step 2: Configure Claude Desktop**
+
+Edit `claude_desktop_config.json` with the following configuration:
+
+```
+{
+  "mcpServers": {
+    "memmachine": {
+      "command": "docker",
+      "args": [
+        "exec",
+        "-e",
+        "MM_USER_ID=Your Name",
+        "-i",
+        "memmachine-app",
+        "/app/.venv/bin/memmachine-mcp-stdio"
+      ],
+      "env": {
+        "MEMORY_CONFIG": "/app/configuration.yml",
+        "PYTHONUNBUFFERED": "1"
+      }
+    }
+  }
+}
+```
+
+Replace `Your Name` with your desired user ID. The `memmachine-app` is the default container name created by the Docker Compose setup.
+
+**Configuration Details:**
+- `memmachine-app`: The Docker container name (default from `memmachine-compose.sh`)
+- `MEMORY_CONFIG`: Path to the configuration file inside the container
+- `MM_USER_ID`: Your user identifier for memory sessions
+- `PYTHONUNBUFFERED`: Ensures immediate output from Python
+
+#### Option 2: Using UV (Development Environment)
+
+Here is an example of working in the development environment with `uv`.  In order to call the command,
+you need to have `uv` installed and issue `uv build` to build the project first.
