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

 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.
+===== On a connected, fully-synced computer =====
+Create a new, blank wallet that cannot store private keys. You can do so using the GUI or with the following console command:
+<code>
+bitcoin-cli createwallet walletname true true
+</code>
+Then, import the descriptors in your wallet:
+<code>
+bitcoin-cli -rpcwallet="walletname" importdescriptors '[{ "desc": "<my descriptor>", "timestamp":1455191478, "internal": true }, { "desc": "<my desccriptor 2>", "label": "example 2", "timestamp": 1455191480 }]'
+</code>
+If the original wallet already exists for a long time, the import may take a very long time and even time out, but will continue in the background. You can check the progress in the debug log. The blockchain will be checked as far back as needed to see if there are any addresses that match the descriptor.
