Hi Omer,
Many of the vocabulary files must be obtained manually from VSAC. This is outlined in the referenced documentation. Unfortunately there is no video guide.
The swagger API referenced can be used as per our configuration, or, once deployed locally, you can use it after updating the URL to your local server with the local configuration. You could also use something like postman, the bundled static angular app, or hitting the end point from your own application.
Thanks,
Dan
