+# GitLab Set Status
+
+GitLab Set Status is part of a collection of GitLab tasks to help working
+with the [GitLab API](https://docs.gitlab.com/ee/api/).
+
+## Set Status on a Commit/MR
+
+The `gitlab-set-status` task uses the [commit api](https://docs.gitlab.com/ee/api/commits.html#post-the-build-status-to-a-commit)
+to mark GitLab commits with a `pending`,`running`, `success`, `failed`, or `canceled` state, which is then reflected in merge requests involving those commits.
+
+Statuses include as well a `description`, a `target_url` and a `coverage`, to give the user
+informations about the CI statuses or a direct link to the full log.
+
+### Install the Task
+
+```shell
+kubectl apply -f https://api.hub.tekton.dev/v1/resource/tekton/task/gitlab-set-status/0.2/raw
+```
+
+### Parameters
+
+* **STATE** (string): The state of the status. Can be one of the following `pending`, `running`, `success`, `failed`, or `canceled`.
+* **GITLAB_TOKEN_SECRET_NAME** (string, optional): The name of the kubernetes secret that contains the GitLab access token. _default:_ `gitlab-api-secret`
+* **GITLAB_TOKEN_SECRET_KEY** (string, optional): The key within the kubernetes secret that contains the GitLab token. _default:_ `token`
+* **SHA** (string): The commit SHA to set the status for.
+* **TARGET_URL** (string): The target URL to associate with this status. This URL will
+  be linked from the GitLab UI to allow users to easily see the source of the
+  status. For example you can link to a
+  [dashboard](https://github.com/tektoncd/dashboard) URL so users can follow a
+  Pipeline/Task run.
+* **GITLAB_HOST_URL** (string, optional): The GitLab host domain. _default:_ `gitlab.com`
+* **API_PATH_PREFIX** (string, optional): The GitLab Enterprise has a prefix for the API path. _default:_ `/api/v4`
+* **REPO_FULL_NAME** (string, optional): The GitLab repository full name. _default:_ `tektoncd/catalog`
+* **DESCRIPTION** (string): A short description of the status. _e.g:_ `Building your MR`
+* **CONTEXT** (string, optional): The GitLab context, A string label to differentiate this status
+  from the status of other systems. _e.g:_ `continuous-integration/tekton`
+* **COVERAGE** (string, optional): The total code coverage. Should be a float string.  _default:_ `""`
+
+## Platforms
+
+The Task can be run on `linux/amd64` platform.
