## What it is
The source repository for the Devicetree Specification, a standard for describing hardware in embedded systems, built with Sphinx and LaTeX. It produces the official PDF and HTML releases of the specification document.

## Use cases
- read the official devicetree specification
- build the devicetree spec as PDF or HTML
- contribute patches to the devicetree specification
- learn how hardware is described for embedded Linux
- reference devicetree binding syntax

## When to choose
- you need the authoritative Devicetree Specification document
- you want to contribute to or build the spec from source
- you are developing firmware or OS support for devicetree-based hardware

## When to avoid
- you need a devicetree compiler or runtime tool (use dtc instead)
- you want a library for parsing devicetree blobs
- you need Linux kernel documentation rather than the spec itself

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation
- domain: embedded-systems, hardware, documentation, developer-tools
- platform: cross-platform, python
- tags: devicetree, specification, sphinx, embedded-hardware, firmware
