 Within `hapi-fhir-jpaserver-starter`, create a generic class (that does not extend or implement any classes or interfaces), add the `@Operation` as a method within the generic class, and then register the class as a provider using `RestfulServer.registerProvider()`.
 
+## Runtime package install
+
+It's possible to install a FHIR Implementation Guide package (`package.tgz`) either from a published package or from a local package with the `$install` operation, without having to restart the server. This is available for R4 and R5.
+
+This feature must be enabled in the application.yaml (or docker command line):
+
+```yaml
+hapi:
+ fhir:
+ ig_runtime_upload_enabled: true
+```
+
+The `$install` operation is triggered with a POST to `[server]/ImplementationGuide/$install`, with the payload below:
+
+```json
+{
+ "resourceType": "Parameters",
+ "parameter": [
+ {
+ "name": "npmContent",
+ "valueBase64Binary": "[BASE64_ENCODED_NPM_PACKAGE_DATA]"
+ }
+ ]
+}
+```
