The document discusses using process automation with and without code using Salesforce Visual Workflow. It provides an introduction to Visual Workflow and examples of use cases including simple flows, autolaunched flows, flows on the Lightning Experience home and record detail pages, using packaged flows, and exposing flows through REST APIs. Live demonstrations are given of reservation flows, a survey flow, and creating an invoice using a third-party package. The key takeaway is that Visual Workflow allows collecting and displaying data through a user interface and extending functionality with code.
