Thanks! Good change! Can you rebase against master? I changed something in the Options interface at line 9.

You should also add sessionToken?: string to that interface.

Also, in the readme, under the Connect header, add the following block at the bottom of that section.

Or provide a sessionToken if you want to use temporary credentials.

db.connect({
   accessKeyId: 'accessKeyId',
   region: 'us-west-1'
});
