+If your account does not yet have a payment plan, you'll be prompted to choose one after your email address has been verified. You will need a payment plan in order to provision your space. You can use the following code to wait for a payment plan to be selected:

+If provisioning succeeds, you're ready to use the Space. Save your space to your agent's state store:
 
-Create a delegation of authority from the space to your client, and add it to your client so future invocations can use it as authorization
 ```js
-const spaceAuthorizesClient = await space.createAuthorization(client)
-await client.addSpace(spaceAuthorizesClient)
+await space.save()
 ```
 
-Set the space as your "current" space using the [`setCurrentSpace` method][docs-Client#setCurrentSpace], passing in the DID of the `space` object you created above. This way, any future method calls on `client` will default to storing with `space`.
+If your agent has no other spaces, saving the space will set it as the "current space" in your agent. If you already have other spaces, you may want to set it as the current:
 
 ```js
 await client.setCurrentSpace(space.did())
 ```
 
+One last thing - now that you've saved your space locally, it's a good idea to setup recovery, so that when you move to a different device you can still access your space: 
+
+```js
+const recovery = await space.createRecovery(account.did())
+await client.capability.access.delegate({
+  space: space.did(),
+  delegations: [recovery],
+})

 #### Delegating from Space to Agent
 
 In order to store data with w3up, your Agent will need a delegation from a Space. This automatically happens if you called `createSpace`. However, if you are initializing the client with a previously created Space, you can `login(email)` then claim a delegation granted to the account associated with your email:
