+# MinIO Containers
+
+Test containers can be used to automatically instantiate and manage [MinIO](https://min.io) containers.
+
+## Usage example
+
+Create a `MinIOContainer` to use it in your tests:
+<!--codeinclude-->
+[Starting a MinIO container](../../modules/minio/src/test/java/org/testcontainers/containers/MinIOContainerTest.java) inside_block:minioContainer
+<!--/codeinclude-->
+
+The [MinIO Java client](https://min.io/docs/minio/linux/developers/java/API.html) can be configured with the container as such:
+<!--codeinclude-->
+[Configuring a MinIO client](../../modules/minio/src/test/java/org/testcontainers/containers/MinIOContainerTest.java) inside_block:configuringClient
+<!--/codeinclude-->
+
+If needed the username and password can be overridden as such:
+<!--codeinclude-->
+[Overriding a MinIO container](../../modules/minio/src/test/java/org/testcontainers/containers/MinIOContainerTest.java) inside_block:minioOverrides
+<!--/codeinclude-->
+
+## Adding this module to your project dependencies
+
+Add the following dependency to your `pom.xml`/`build.gradle` file:
+
+=== "Gradle"
+```groovy
+testImplementation "org.testcontainers:minio:{{latest_version}}"
+```
+
+=== "Maven"
+```xml
+<dependency>
+<groupId>org.testcontainers</groupId>
+<artifactId>minio</artifactId>
+<version>{{latest_version}}</version>
+<scope>test</scope>
+</dependency>
+```
