-# Automate Jenkins Installation on Docker for Testing
+# Automated Jenkins Installation on Docker for Testing with Kubernetes Integration
+
+## Prerequisites
+
+- Docker must be installed.
+- Kubernetes must be installed.
+
+## Installation
+
+To set up a new Jenkins instance, execute the following command:
+```bash
+./test/jenkins/install.sh
+```
+
+## Testing
+
+Follow these steps to test the Kubernetes integration:
+
+1. Create a pipeline named `test-kubernetes-agent`.
+2. Insert the provided pipeline definition script:
+
+```groovy
+pipeline {
+    agent {
+        kubernetes {
+            yaml '''
+        apiVersion: v1
+        kind: Pod
+        spec:
+          containers:
+          - name: maven
+            image: maven:alpine
+            command:
+            - cat
+            tty: true
+          - name: node
+            image: node:16-alpine3.12
+            command:
+            - cat
+            tty: true
+        '''
+        }
+    }
+    stages {
+        stage('Run maven') {
+            steps {
+                container('maven') {
+                    sh 'mvn -version'
+                }
+                container('node') {
+                    sh 'npm version'
+                }
+            }
+        }
+    }
+}
+```
+
+3. Execute the pipeline; two agents should be deployed on the Kubernetes cluster.
