 Data Plane API is generated using [go-swagger](https://github.com/go-swagger/go-swagger) from the swagger spec found [here](https://github.com/haproxytech/client-native/blob/master/specification/build/haproxy_spec.yaml) using the following command.
 
 ```
-make swagger
+make generate
 ```
 or if you prefer to run it directly (not in docker)
 ```
-make swagger-native
+make generate-native
 ```
 
+`make generate-native` must also be used if you are using local client-native on disk (you have `replace github.com/haproxytech/client-native/v2 => ../client-native` in go.mod file)
+
 This command generates some of the files in this project, which are marked with // Code generated by go-swagger; DO NOT EDIT.
 comments at the top of the files. These are not to be edited, as they are overwritten when specification is changed and the above-mentioned command is run. If you want to change those files, please change the specification where necessary and then generate them again.
