 ### How to debug OpenAPI Generator?
 
-You can leverage the following debug flags when generating the libraries:
-- [debugOpenAPI] prints the OpenAPI specification as interpreted by the codegen
-- [debugModels] prints models passed to the template engine
-- [debugOperations] prints operations passed to the template engine
-- [debugSupportingFiles] prints additional data passed to the template engine
+Please refer to https://github.com/OpenAPITools/openapi-generator/blob/master/docs/debugging.md
 
-Here is an example using `debugModels`:
-```
-mvn clean package
-java -DdebugModels=true -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate \
-  -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.json \
-  -g ruby -o /var/tmp/ruby/
