# ScreenJSON Documentation

> Reference documentation for the ScreenJSON toolchain — schema, CLI tools, viewer, and Greenlight batch microservice.

ScreenJSON is an open schema for screenplay data and a set of tools that produce, consume, render, and manage it.

These docs are **reference**, grounded in what each tool actually does. Every flag, environment variable, task, and endpoint below matches the released source. For narrative articles, audience guides, and how-tos, see [screenjson.com](https://screenjson.com).
