Go to the demo - you will arrive at the demo home page.
Click on My Circles at the top left - next to the Circle logo.
This will open the demo site.
On the My Circles menu, select Create a Circle.
Select Invite - a dialogue box will be presented with two codes.
Speak, text or otherwise communicate these two codes to your demo partner - or anyone that you would like to invite to your Circle.
To accept the invitation, your demo partner selects Accept Invite and inputs the two codes.
After confirmation, the AES 256 keys for your Circle are securely shared to your demo partner.
Now you can share files securely within the Circle, encrypted end-to-end with the AES 256 key.
