 * Security Information: The SUSHI Security Information can be found in [SECURITY.md](SECURITY.md).
 * Compliance Information: SUSHI supports creating Implementation Guides for FHIR R4, FHIR R4B, and FHIR R5. While SUSHI performs basic validation to help users author FSH that will produce valid FHIR artifacts, it is not intended to be a full-featured validator. For example, SUSHI does validate paths and cardinalities, but does not validate author-provided FHIRPath expressions, terminological compliance, or slice membership. Authors are encouraged to use a full-featured validator, such as the one found in the IG Publisher, to test their final FHIR outputs. The SUSHI source code includes a comprehensive suite of unit tests to test SUSHI's own behavior and compliance with FHIR, which can be found in the [test](test) directory.

 SUSHI supports publishing implementation guides via the new template-based IG Publisher. The template-based publisher is still being developed by the FHIR community. See the [Guidance for HL7 IG Creation](https://build.fhir.org/ig/FHIR/ig-guidance/) for more details.
 
 Based on the inputs in FSH files, **sushi-config.yaml**, and the IG project directory, SUSHI populates the output directory. See the [documentation on IG Project with SUSHI](https://fshschool.org/docs/sushi/project/#ig-projects) for more information on using SUSHI to generate IGs.
