+## Using the Goose Docker Image
+
+You can now use the official Goose Docker image to run Goose in a containerized environment. Follow the instructions below to build and run the Goose Docker image.
+
+### Building the Docker Image
+
+To build the Goose Docker image, run the following command in the root directory of the repository:
+
+```sh
+docker build -t goose:latest .
+```
+
+### Running the Docker Image
+
+To run the Goose Docker image, use the following command:
+
+```sh
+docker run --rm -it goose:latest
+```
+
+This will start the Goose CLI in an interactive terminal session.
+
+You can also pass additional arguments to the Goose CLI by appending them to the `docker run` command. For example, to run a specific Goose command, use:
+
+```sh
+docker run --rm -it goose:latest <command>
+```
+
+Replace `<command>` with the desired Goose command and its arguments.
