+# Dependencies license management with GitLab CI/CD
+
+NOTE: **Note:**
+In order to use this tool, a [GitLab Ultimate][ee] license
+is needed.
+
+This example shows how to run the License Management tool on your
+project's dependencies by using GitLab CI/CD.
+
+First, you need GitLab Runner with [docker-in-docker executor](https://docs.gitlab.com/ee/ci/docker/using_docker_build.html#use-docker-in-docker-executor).
+You can then add a new job to `.gitlab-ci.yml`, called `license_management`:
+
+```yaml
+license_management:
+  image: registry.gitlab.com/gitlab-org/security-products/license-management:latest
+  allow_failure: true
+  script:
+    - /run.sh .
+  artifacts:
+    paths: [gl-license-report.json]
+```
+
+The above example will create a `license_management` job in the `test` stage and will create the required report artifact. Check the
+[Auto-DevOps template](https://gitlab.com/gitlab-org/gitlab-ci-yml/blob/master/Auto-DevOps.gitlab-ci.yml)
+for a full reference.
+
+
+TIP: **Tip:**
+Starting with [GitLab Ultimate][ee] 10.8, this information will
+be automatically extracted and shown right in the merge request widget. To do
+so, the CI job must be named `license_management` and the artifact path must be
+`gl-license-report.json`. Make sure your pipeline has a stage nammed `test`,
+or specify another existing stage inside the `license_management` job.

+# License Management
+
+> [Introduced][ee-5483] in [GitLab Ultimate][ee] 10.8.
+
+## Overview
+
+If you are using [GitLab CI/CD][ci], you can search your project dependencies for their licenses
+using License Management, either by
+including the CI job in your [existing `.gitlab-ci.yml` file][cc-docs] or
+by implicitly using [Auto License Management](../../../topics/autodevops/index.md#auto-dependency-scanning)
+that is provided by [Auto DevOps](../../../topics/autodevops/index.md).
+
+Going a step further, GitLab can show the licenses list right in the merge
+request widget area.
+
+## Use cases
+
+It helps you find licenses that you don't want to use in your project and see
+which dependencies use them. For example, your application is using an external (open source)
+library whose license is incompatible with yours.
+
+## Supported languages and dependency managers
+
+The following languages and dependency managers are supported.
+
+| Language (package managers)                                                 |
+|-----------------------------------------------------------------------------|
+| Bower ([Bower](https://bower.io/))                                          |
+| Go ([Godep](https://github.com/tools/godep), go get)                        |
+| Java ([Gradle](https://gradle.org/), [Maven](https://maven.apache.org/))    |
+| JavaScript ([npm](https://www.npmjs.com/))                                  |
+| .NET ([Nuget](https://www.nuget.org/))                                      |
+| Python ([pip](https://pip.pypa.io/en/stable/))                              |
+| Ruby ([gem](https://rubygems.org/))                                         |
+
+## How it works
+
+First of all, you need to define a job named `license_management` in your
+`.gitlab-ci.yml` file. [Check how the `license_management` job should look like][cc-docs].
+
+In order for the report to show in the merge request, there are two
+prerequisites:
+
+- the specified job **must** be named `license_management`
+- the resulting report **must** be named `gl-license-report.json`
+  and uploaded as an artifact
+
+The `license_management` job will search the application dependencies for licenses,
+the resulting JSON file will be uploaded as an artifact, and
+GitLab will then check this file and show the information inside the merge
+request.
