From nothing to the storefront in four steps.
Reaching Crown takes four steps.
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. Crown works fine at Safest.
Copy an address from the verified list, never type a fifty-six character string by hand. Open it in Tor Browser, and before your password hold the address against the one the login captcha prints. Match means genuine, mismatch means close the tab.
