+### Jenkins
+#### Installing Jenkins
+I installed Jenkins with docker-compose.
+
+```
+ jenkins:
+    image: 'jenkins/jenkins:lts'
+    privileged: true
+    user: root
+    ports:
+      - 8080:8080
+      - 50000:50000
+    container_name: jenkins
+    volumes:
+      - /tmp/jenkins:/var/jenkins_home #Remember that, the tmp directory is designed to be wiped on s$
+      - /var/run/docker.sock:/var/run/docker.sock
+    depends_on:
+      -  sonarqube
+
+```
+#### Configuring Jenkins to work with Gitlab
+I builded my integration based on [this](https://docs.gitlab.com/ee/integration/jenkins.html) guide.
