- - - - Save — stores your changes and creates a new workflow version.You can save as many times as you want while editing and testing. Auto save is also enabled so if you forget to save, we have you covered.
      - Publish — makes a specific version live in production.Only the published version runs automatically.
      - Important: Editing a workflow after publishing does NOT affect production until you publish again.
  - - - When to use workflows (Manual vs Automatic execution)
        
        Manual execution : You run the workflow using Execute Workflow.
        Perfect for testing workflow logic, checking node outputs, and making adjustments.
        
        Automatic execution: The workflow runs automatically when a triggering event or schedule occurs.
        To enable automatic execution, add a trigger node and publish the workflow.
      - Common use cases
        
        moving or syncing data between apps
        
        updating CRM or database records
        
        scheduling recurring tasks or reports
        
        using AI nodes to process data
        
        sending alerts and notifications
        
        connecting services and APIs
      - Workflow types in n8n
        
        Manual Execution: Runs when you click Execute Workflow. Used for testing or workflows without a trigger.
        
        Automatic Execution: Runs automatically when a Trigger, Webhook or polling detects an event.
        
        Scheduled Execution: Runs on a set schedule. Ideal for daily/weekly recurring tasks.
    - - A node is a single step in your workflow.
      - Each node can:
        
        Fetch data
        
        Process data
        
        Send data
      - Nodes are connected in a sequence: [Node] → [Node] → [Node]
        All nodes together make the workflow run smoothly, like building blocks of automation.
      - TYPES
        
        TRIGGER NODES:
        
        start the workflow and provide the first data.
        
        Examples: New Telegram message, new email, new row in Google Sheets.
        
        [Trigger Node] → [Next Node]
        
        ACTION/APP NODES:
        
        act on data:add, update, delete, send.
        
        Examples:Slack, DB, Twitter
        
        [Trigger] → [Action] → [Next]
        
        CORE NODES:
        
        handle workflow logic. They can check conditions, schedule actions, or transform data.
        
        Examples:IF node, Set node, HTTP Request node.
        
        [Trigger] → [IF Node] → [Action]
        
        CLUSTER NODES: are groups of nodes working together, mainly in AI workflows.
        [Root Node] → [Language Model] → [Parser] → [Output]
        
        CONNECTIONS AND DATA FLOWS:
        
        Connections pass data between nodes (JSON items).
        
        [Node A] → [Node B] → [Node C]
        
        Create: drag from dot.Delete: click connection.
