Documentation
These are the same articles the tool ships in its built-in Help section — published straight from the source, so the website and the app never disagree.
Basics
From an empty screen to a flow that runs, in four steps.
Frontmatter, prose and executable step blocks.
What every part of the screen does.
Any frontmatter property you like, editable from the document.
A folder of flows as a table you can sort, filter and search.
Writing flows
Every key you can use inside a step block.
Where the callable methods come from, and how they document themselves.
Flow memory: what one step writes, the next one reads.
Assert the status and the body, including JavaScript expressions.
Assert on messages produced asynchronously, out of band.
Fake what a dependency answers, so you can test locally.
Reference
Integrations
Generate a flow from a description, or rewrite one with the magic wand.
Link a flow to a Test issue, and pull the tests of a project.
Drive a web application from a flow. Experimental.
One env file per application per environment — nothing in the repo.
