+### Docker
+
+Build and run the MCP server in a container:
+
+```bash
+docker build -t chrome-devtools-mcp .
+docker run --rm -i chrome-devtools-mcp
+```
+
+The container image installs Google Chrome and starts the MCP server in headless
+mode by default. The bundled command also includes `--no-sandbox` and
+`--disable-dev-shm-usage`, which are commonly needed in containerized
+environments. Extra CLI flags can be appended to `docker run`, for example:
+
+```bash
+docker run --rm -i chrome-devtools-mcp --log-file=/tmp/chrome-devtools.log
+```
