+In the Artifact Registry in Harness, **Triggers** automate actions based on events related to your artifacts, and allow you to streamline workflows by responding dynamically to changes in your artifact repositories.
+
+## Types of Triggers
+1.	**Artifact Ingestion**
+    - Executes when a new artifact is pushed to the registry.
+    - Useful for automating deployments or notifying downstream systems.
+2.	**Artifact Update**
+    - Fires when an existing artifact is updated.
+    - Can be used to track and validate changes.
+3.	**Artifact Deletion**
+    - Triggers when an artifact is deleted from the registry.
+    - Helps with cleanup automation or compliance monitoring.
+
+## Use Cases for Triggers
+- **CI/CD Automation:** Start a pipeline when a new artifact is ingested.   
+- **Version Control:** Notify teams when a new version of an artifact is available.
+- **Security & Compliance:** Scan artifacts when they are pushed or updated.
+- **Cleanup & Retention Policies:** Automatically remove outdated artifacts.
