Build for Light
Light is a calm, simple admin on top of Mage-OS and Magento Open Source. Your module extends it the Magento way, with DI items and layout blocks, and the checks in this guide keep it working as Light grows.
Developer guide
What Light is, how modules plug in, and the rules every module follows.
Getting started
A first Light app in about 15 minutes, as a bridge or built into your module.
Design system
Page layout, components, JS modules and forms for your own Light pages.
Build with an AI assistant
The Markdown of every page, prompts that work, and an AGENTS.md for your repository.
For LLMs: llms.txt lists every page, and llms-full.txt holds the whole guide as Markdown.
