From nothing to the storefront in four steps.
Reaching Awazon takes four steps, and the shop-style interface makes the rest easy once you are in.
Download Tor Browser only from the official Tor Project site, verify the signature on the first install, and set the security level to Safest. A normal browser cannot open an onion address. Awazon works fine at Safest.
Copy a mirror from the verified list, never type a fifty-six character string by hand. Open it in Tor Browser. The login shows a case-sensitive captcha with a decoy field beside the real one, so read the characters, type into the visible field, and confirm the address matches your bar before your password.
