Dear Renyi ,
Thank you for your request.
The procedure on how to use the custom resource file in iink SDK Web was indeed missing, so we have just updated our documentation to fix this.
In Web, you don't have to copy the returned .res file into a directory but to upload it into your cloud dashboard.
You can now find the procedure explaining how to do it here.
Feel free to contact us if you have any further question.
Regards,
Gwenaëlle
Thanks!

I uploaded a .txt file and the resource builder returned a .res file. I'm not sure which directory to put it in.
