-#### Use locally built JAR
-In order to use a locally built jar of the generator CLI, you can copy the jar from your local build (i.e. if you were to `build` this repository it would be in `~/openapi-generator/modules/openapi-generator-cli/target/openapi-generator-cli.jar`) into `./node_modules/@openapitools/openapi-generator-cli/versions/` and change the `version` in the `openapitools.json` file to the base name of the jar file.
-E.g.:
-```sh
-cd openapi-generator
-./mvnw clean package
-cp ./modules/openapi-generator-cli/target/openapi-generator-cli.jar /your/project/node_modules/@openapitools/openapi-generator-cli/versions/my-local-snapshot.jar
-```
-and then:
-```json
-{
-  "$schema": "./node_modules/@openapitools/openapi-generator-cli/config.schema.json",
-  "spaces": 2,
-  "generator-cli": {
-    "version": "my-local-snapshot",
-  }
-}
-```
-
-#### Use nightly `SNAPSHOT` build
-Change your `openapitools.json` to:
-
-```json
-{
-  "$schema": "node_modules/@openapitools/openapi-generator-cli/config.schema.json",
-  "spaces": 2,
-  "generator-cli": {
-    "version": "7.9.0-20240829.123431-22",

-    }
-  }
-}

-(example is with a snapshot of `7.9.0`, please change the `version` and `downloadUrl` accordingly)

+
+### How do I migrate from the Swift 5 generator to the swift 6 generator?
+
+- Change the generator to the new `swift6` generator, e.g. `openapi-generator generate -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml -g swift6 -o /tmp/test/`
+- Check the `swift6` [URLSession](https://github.com/OpenAPITools/openapi-generator/tree/master/samples/client/petstore/swift6/urlsessionLibrary) and [Alamofire](https://github.com/OpenAPITools/openapi-generator/tree/master/samples/client/petstore/swift6/alamofireLibrary) samples.
+- The infrastructure files have been moved to a new directory called `Infrastructure`. Please delete the old ones.
+- The `AnyCodable` dependency has been removed and replaced with a new enum called `JSONValue`, allowing you to use this generator without external dependencies.
+- The `Combine` response is now deferred by default, meaning the request will only start when you begin listening to it. To restore the previous behavior, set the `combineDeferred` flag to `false`.
+- A new configuration, `apiStaticMethod`, allows you to use instance methods instead of class methods for API calls. For more information, check the sample project [apiNonStaticMethod](https://github.com/OpenAPITools/openapi-generator/tree/master/samples/client/petstore/swift6/apiNonStaticMethod).
+- The new default response is based on async/await. To revert to the previous behavior, set the `responseAs` flag to `ObjcBlock`.
+- The default project structure now follows the SPM (Swift Package Manager) structure. To revert to the old structure, set the `useSPMFileStructure` flag to `false`.
+- The former `{{projectName}}API` is now called `OpenAPIClient`.
+- You can now set a request interceptor and retrier by configuring `OpenAPIClient.shared.interceptor`, making authenticated requests easier to manage.
