 Once you have a valid token/tokenSet saved you can set the tokenSet on the client without going through the callback by calling `setTokenSet`.
 
 For example - once a user authenticates you can refresh the token (which will also set the new token on the client) to make authorized api calls.
+
+There are two ways to refresh a token.
+
+```js
+// refreshToken()
+const validTokenSet = await xero.refreshToken()
+```
+
+If you already generated a valid access token, you can initialize an empty client and refresh any saved access_tokens by passing the client, secret, and refresh_token to refreshWithRefreshToken()
+```js
+const newXeroClient = new XeroClient()
+const refreshedTokenSet = await newXeroClient.refreshWithRefreshToken(client_id, client_secret, tokenSet.refresh_token)
+```
+
+Making AUthorized API calls:

 ```js
 const tokenSet = getTokenSetFromDatabase(userId) // example function name
