+### Jenkins
+
+The following snippet can be added to a `Jenkinsfile` to install and analyze images:
+
+```groovy
+        stage('Analyze image') {
+            steps {
+                // Install Docker Scout
+                sh 'curl -sSfL https://raw.githubusercontent.com/docker/scout-cli/main/install.sh | sh -s -- -b /usr/local/bin'
+                
+                // Log into Docker Hub
+                sh 'echo $DOCKER_HUB_PAT | docker login -u $DOCKER_HUB_USER --password-stdin'
+
+                // Analyze and fail on critical or high vulnerabilities
+                sh 'docker-scout cves $IMAGE_TAG --exit-code --only-serverity critical,high'
+            }
+        }
+```
+
+This example assume two secrets to be available to authenticate against Docker Hub, called `DOCKER_HUB_USER` and `DOCKER_HUB_PAT`.
