Any one want to give me the old review? @armab

LGTM - perhaps longer term the access_key_id shouldn't really be mandatory, so that you can actually omit those parameters rather than setting to "None".
Can you sign the CLA first though, before we approve?

[satellite-no]

I've signed it several times trying to get the PR to update. Nothing ever updates or shows I signed the CLA.

Is it associated with the wrong email perhaps? It doesn't even think you are a github user?

Ha, got it! I thought...

good?

[amanda11]

good?

Still failing on CLA Looking at the history of the commits, we need to get the author changed on the previous 2 commits to the same email you used on the update readme, and then it should pass.

Got it! that was a learning experience LOL.
