+# Autodeploy
+
+> [Introduced][mr-8135] in GitLab 8.15.
+
+Autodeploy is an easy way to configure GitLab CI for the deployment of your
+application. GitLab Community maintains a list of `.gitlab-ci.yml`
+templates for various infrastructure providers and deployment scripts
+powering them. These scripts are responsible for packaging your application,
+setting up the infrastructure and spinning up necessary services (for
+example a database).
+
+You can use [project services][project-services] to store credentials to
+your infrastructure provider and they will be available during the
+deployment.
+
+## Supported templates
+
+The list of supported autodeploy templates is available [here][autodeploy-templates].
+
+## Configuration
+
+1. Enable a deployment [project service][project-services] to store your
+credentials. For example, if you want to deploy to a Kubernetes cluster
+you have to enable [Kubernetes service][kubernetes-service].
+1. Configure GitLab Runner to use [docker-in-docker executor][docker-in-docker].
+1. Navigate to the "Project" tab and click "Set up autodeploy" button.

+1. Commit your changes and create a merge request.
+1. Test your deployment configuration using a [Review App][review-app] that was
+created automatically for you.
