Scenarios, modules, and the three module types
The scenario is the recipe. Each module is one step. The data is the baton passed from runner to runner.
Scenario: one trigger point, several possible actions, a visual flowchart, runs automatically; grouped in folders (marketing, sales). Module: one step - Trigger (watch new Gmail, form response, new Sheets row), Action (send email, create CRM contact, update spreadsheet, post to social), Search (find a customer, find a file). Output of one module becomes input of the next.
The two nouns every Make conversation uses.
