+```
+
+* Navigate to the new folder.
+```bash
+cd au-core-demo
+```
+
+* Clone the AU Core IG repository via Git.
+```bash
+git clone git@github.com:hl7au/au-fhir-core.git
+```
+* Clone the AU FHIR Core Inferno repository via Git.
+```bash
+git clone git@github.com:hl7au/au-fhir-core-inferno.git
+```
+* Download the latest release of the IG Publisher software.
+```bash
+curl -L -o publisher.jar https://github.com/HL7/fhir-ig-publisher/releases/download/1.6.28/publisher.jar
+```
+* Generate the original IG archive using the IG Publisher software.
+```bash
+java -jar publisher.jar au-fhir-core/ig.ini
+```
+* Remove all previously generated test suites and existing IG files from the AU FHIR Core Inferno folder.
+```bash
+rm -rf au-fhir-core-inferno/lib/au_core_test_kit/generated/
+rm au-fhir-core-inferno/lib/au_core_test_kit/igs/*.tgz
+```
+* Move the generated package.tgz file to the AU FHIR Core Inferno folder.
+```bash
+cp au-fhir-core/output/package.tgz au-fhir-core-inferno/lib/au_core_test_kit/igs/

+```bash
+cd au-fhir-core-inferno/
+make setup
+make generate
+```
+* In file lib/au-core-test-kit.rb you need to comment **require_relative 'au_core_test_kit/generated/v1.0.0-ballot/au_core_test_suite'** and uncomment **require_relative 'au_core_test_kit/generated/v1.0.0-ci-build/au_core_test_suite'**
