+# Useful Usage Examples
+
+This document provides practical, real-world usage examples for commonly used Jenkins plugins.
+The goal is to help new users understand how these plugins are typically used in day-to-day Jenkins setups.
+
+---
+
+## 1. Git Plugin
+
+### When to use
+The Git plugin is used when your source code is stored in a Git repository such as GitHub, GitLab, or Bitbucket.
+
+### Example: Checkout source code in a Pipeline
+
+```groovy
+pipeline {
+    agent any
+
+    stages {
+        stage('Checkout') {
+            steps {
+                git(
+                    url: 'https://github.com/example/project.git',
+                    branch: 'main'
+                )
+            }
+        }
+    }
+}
+
+
+### Example: Basic CI Pipeline
+
+pipeline {
+    agent any
+
+    stages {
+        stage('Build') {
+            steps {
+                echo 'Building the application'
+            }
+        }
+
+        stage('Test') {
+            steps {
+                echo 'Running tests'
+            }
+        }
+    }
+}
+
+### Example: Using credentials securely in a pipeline
+
+pipeline {
+    agent any
+
+    stages {
+        stage('Deploy') {
+            steps {
+                withCredentials([
+                    string(credentialsId: 'api-token', variable: 'API_TOKEN')
+                ]) {
+                    sh 'echo Deploying with token $API_TOKEN'
+                }
+            }
+        }
+    }
+}
+
+### Example: Send email on build failure
+
+pipeline {
+    agent any
+
+    stages {
+        stage('Build') {
+            steps {
+                error 'Simulated failure'
+            }
+        }
+    }
+
+    post {
+        failure {
+            emailext(
+                subject: 'Build Failed: ${env.JOB_NAME}',
+                body: 'The build has failed. Please check the Jenkins console output.',
+                to: 'team@example.com'
+            )
+        }
+    }
+}
