### Package File

The following package file includes an NPM package file used by many of the FHIR tools. It contains all the value sets, profiles, extensions, list of pages and URLs in the IG, etc., defined as part of this version of the Implementation Guides. This file **SHOULD** be the first choice whenever generating any implementation artifacts since it contains all the rules about what makes the profiles valid. Implementers must still be familiar with the specification content and profiles that apply to create a conformant implementation. See the [validating profiles and resources](http://hl7.org/fhir/R4/validation.html) documentation in FHIR for more information.

### Downloadable Copy of Specification

A downloadable version of this IG is available so it can be hosted locally:

### LLM-Ready View

This is an "LLM-ready" view of the IG pages in Markdown format created from the static HTML pages. This format reduces the IG size and is designed to help an LLM handle the IG contents more easily.

* [llms.txt](llms.txt): An llms.txt manifest — a machine-readable index of the IG's Markdown files.
* [ai.zip](ai.zip): Markdown version of each HTML page bundled in a zip file.
