# YAML reference

A DRE project is YAML and SQL files. Each kind of YAML file has a reference page that lists every key with its type, default and meaning. The pages are generated from the same [JSON Schemas](https://getdre.com/docs/v0.1/editor-setup/) that give editors autocomplete, so they can’t miss a key.
