The document discusses Prefect, an open source Python workflow application framework. It describes why workflows are needed (to interact with many systems, understand and react to events, and standardize workflows). It then explains what Prefect is (a Pythonic workflow application framework for developers) and how it works (as both an open source Python package and cloud-hosted solution for teams). The document demonstrates Prefect through a code example and discusses how it can power customizable activity reminder apps by setting workflows to run on schedules.

2. Why?
We all have workflows.
Modern data stack needs:
1. Interact with many systems
2. Understand and react to events
3. Standardize workflows
