1/ Check if service is available for your TLD:

In [15]: sess.get('https://rdap.gandi.net/domain/rdap.lol').json()['links']
Out[15]: [... {'href': 'https://cdscheck.gandi.net/v1/domains/rdap.lol/cds',
  'rel': 'https://rdap.io/tpda/cdscheck'}]

2/ Publish your CDS and sign it with your existing DNSKEY - make sure everything is signed by the new keys on all nameservers.
The checker is going the validate that as well.

3/ DS check
In [17]: cds.put('https://cdscheck.gandi.net/v1/domains/rdap.lol/cds').text
Out[23]: '{"status": "success", "rel": 99439172}'

The new DS will replace the existing ones at the registry shortly after.
