First, set up a new wallet the usual way. Then, export the descriptors for that wallet via the following console command:

listdescriptors

Do not add true as a parameter, as that would also export your private key descriptors!

Copy the descriptors array to a removable drive. It should look similar to this:

{
    "desc”: "wpkh([66bb13d5/84'/0'/0']xpub6CtDSW4S3XVd5uYp9CgsLTZKQcKieJSmjehcvfVJBSy1rPbkKNU3T6UmZ3mn7DoSsTsM6uH8ZKem7LQh3PHyrBAtZopSvF2tonEE7foTWFe/1/*)#a9twa6j5",
    "timestamp": 1647182091,
    "active": true,
    "internal": true,
    "range": [
    0,
    999
    ],
    "next": 0
    },
    {
    "desc": "wpkh([66bb13d5/84'/0'/0']xpub6CtDSW4S3XVd5uYp9CgsLTZKQcKieJSmjehcvfVJBSy1rPbkKNU3T6UmZ3mn7DoSsTsM6uH8ZKem7LQh3PHyrBAtZopSvF2tonEE7foTWFe/0/*)#v3w0q0zv",
    "timestamp": 1647182091,
    "active": true,
    "internal": false,
    "range": [
    0,
    1000
    ],
    "next": 1
    }

Note that you should only see descriptors with the key prefix xpub. If you see the prefix 'xprv' instead, you have also exported your private descriptors.
