So you own a Layer, now how do you use it?
Go to async.market and log into your account. Hover over your name in the upper-right corner and click on "Make Layer Change".
You will find all the Async Layers you own, along with their changeable attributes. Select the change you'd like and then hit "Update". This will create a transaction for you to sign.
After the transaction clears you should see your update reflected on the Master within 5 minutes. You can see exactly when the change occurs by looking at the #art-feed channel in our Discord! This channel automatically posts whenever there has been a Layer change triggered.
