Rule suggested by Ivan Goncharov.
Documentation is an excellent GraphQL advantage. In order to make it actual, its description creates directly in the code of GraphQL types. Documentation is available through the introspection.
By the GraphQL specification, you can use
markdown for the
description property of types, fields, and arguments.
Most GraphQL clients (GraphiQL, Playground, Altair, VSCode plugins) can correctly display
markdown to end users.
