+# Argo Cheatsheet
+
+**1. Introduction:**
+
+- Argo CD is a declarative GitOps continuous delivery tool for Kubernetes. It automates application deployment and lifecycle management using Git as the source of truth.
+
+**2. Key Concepts:**
+
+- **Application:** Represents a deployed Kubernetes resource defined in Git.
+- **Repository:** Git repository containing Kubernetes manifests or Helm charts.
+- **Sync:** Process of applying Git state to the cluster.
+- **Health Status:** Indicates if resources are healthy, degraded, or missing.
+
+**3. Basic `.argo/config.yml` Example:**
+
+- **YAML Syntax:**
+
+  ```yaml
+    apiVersion: argoproj.io/v1alpha1
+    kind: Application
+    metadata:
+    name: sample-app
+    namespace: argocd
+    spec:
+    project: default
+
+    source:
+        repoURL: https://github.com/example/app-config.git
+        targetRevision: main
+        path: manifests
+
+    destination:
+        server: https://kubernetes.default.svc
+        namespace: production
+
+    syncPolicy:
+        automated:
+        prune: true
+        selfHeal: true
+  ```
+
+
+**4. Deployment Methods:**
+
+- **Manual Sync:** Click SYNC in UI or run:
+                        argocd app sync sample-app
+- **Automated Sync:** Enable in manifest:
+  ```yaml
+    syncPolicy:
+    automated:
+        prune: true
+        selfHeal: true
+  ```
