+# Jenkins CI (deprecated) service
+
+>**Note:** In GitLab 8.3, Jenkins integration using the
+[GitLab Hook Plugin](https://wiki.jenkins.io/display/JENKINS/GitLab+Hook+Plugin)
+was deprecated in favor of the
+[GitLab Plugin](https://wiki.jenkins.io/display/JENKINS/GitLab+Plugin).
+Please use documentation for the new [Jenkins CI service](jenkins.md).
+
+Integration includes:
+
+* Trigger Jenkins build after push to repo
+* Show build status on Merge Request page
+
+Requirements:
+
+* [Jenkins GitLab Hook plugin](https://wiki.jenkins.io/display/JENKINS/GitLab+Hook+Plugin)
+* git clone access for Jenkins from GitLab repo (via ssh key)
+
+## Jenkins
+
+1. Install [GitLab Hook plugin](https://wiki.jenkins.io/display/JENKINS/GitLab+Hook+Plugin)
+2. Set up jenkins project

+
+## GitLab
+
+In GitLab, perform the following steps.
+
+### Read access to repository
+
+Jenkins needs read access to the GitLab repository. We already specified a
+private key to use in Jenkins, now we need to add a public one to the GitLab
+project. For that case we will need a Deploy key. Read the documentation on
+[how to set up a Deploy key](../ssh/README.md#deploy-keys).
+
+### Jenkins service
+
+Now navigate to GitLab services page and activate Jenkins
+
+![screen](img/jenkins_gitlab_service.png)
+
+Done! Now when you push to GitLab - it will create a build for Jenkins.
+And also you will be able to see merge request build status with a link to the Jenkins build.
+
+### Multi-project Configuration
+
+The GitLab Hook plugin in Jenkins supports the automatic creation of a project
+for each feature branch. After configuration GitLab will trigger feature branch
+builds and a corresponding project will be created in Jenkins.
+
+Configure the GitLab Hook plugin in Jenkins. Go to 'Manage Jenkins' and then
+'Configure System'. Find the 'GitLab Web Hook' section and configure as shown below.
