+# Docker Model Runner
+
+This module helps connect to [Docker Model Runner](https://docs.docker.com/desktop/features/model-runner/)
+provided by Docker Desktop 4.40.0.
+
+## DockerModelRunner's usage examples
+
+You can start a Docker Model Runner proxy container instance from any Java application by using:
+
+<!--codeinclude-->
+[Create a DockerModelRunnerContainer](../../core/src/test/java/org/testcontainers/containers/DockerModelRunnerContainerTest.java) inside_block:container
+<!--/codeinclude-->
+
+### Pulling the model
+
+Pulling the model is as simple as:
+
+<!--codeinclude-->
+[Pull model](../../core/src/test/java/org/testcontainers/containers/DockerModelRunnerContainerTest.java) inside_block:pullModel
+<!--/codeinclude-->
+
+## Adding this module to your project dependencies
+
+*Docker Model Runner support is part of the core Testcontainers library.*
+
+Add the following dependency to your `pom.xml`/`build.gradle` file:
+
+=== "Gradle"
+    ```groovy
+    testImplementation "org.testcontainers:testcontainers:{{latest_version}}"
+    ```
+=== "Maven"
+    ```xml
+    <dependency>
+        <groupId>org.testcontainers</groupId>
+        <artifactId>testcontainers</artifactId>
+        <version>{{latest_version}}</version>
+        <scope>test</scope>
+    </dependency>
+    ```
