+# Nats
+
+Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+## Introduction
+
+The Testcontainers module for nats.
+
+## Adding this module to your project dependencies
+
+Please run the following command to add the nats module to your Go dependencies:
+
+```
+go get github.com/testcontainers/testcontainers-go/examples/nats
+```
+
+## Usage example
+
+<!--codeinclude-->
+[Creating a nats container](../../examples/nats/nats.go)
+<!--/codeinclude-->
+
+<!--codeinclude-->
+[Test for a nats container](../../examples/nats/nats_test.go)
+<!--/codeinclude-->
+
+## Module reference
+
+The nats module exposes one entrypoint function to create the nats container, and this function receives two parameters:
+
+```golang
+func RunContainer(ctx context.Context, opts ...testcontainers.ContainerCustomizer) (*natsContainer, error)
+```
+
+- `context.Context`, the Go context.
+- `testcontainers.ContainerCustomizer`, a variadic argument for passing options.
+
+### Container Options
+
+When starting the nats container, you can pass options in a variadic way to configure it.
+
+#### Image
+
+If you need to set a different nats Docker image, you can use `testcontainers.WithImage` with a valid Docker image
+for nats. E.g. `testcontainers.WithImage("docker.io/nats:latest")`.
+
+#### Wait Strategies
+
+If you need to set a different wait strategy for nats, you can use `testcontainers.WithWaitStrategy` with a valid wait strategy
+for nats.
+
+!!!info
+    The default deadline for the wait strategy is 60 seconds.
+
+At the same time, it's possible to set a wait strategy and a custom deadline with `testcontainers.WithWaitStrategyAndDeadline`.
+
+#### Docker type modifiers
+
+If you need an advanced configuration for nats, you can leverage the following Docker type modifiers:
+
+- `testcontainers.WithConfigModifier`
+- `testcontainers.WithHostConfigModifier`
+- `testcontainers.WithEndpointSettingsModifier`
+
+Please read the [Create containers: Advanced Settings](../features/creating_container.md#advanced-settings) documentation for more information.
+
+### Container Methods
+
+The nats container exposes the following methods:
