On Windows or Mac, go to [binaryFate's GPG key](https://raw.githubusercontent.com/monero-project/monero/master/utils/gpg_keys/binaryfate.asc), which he uses to sign the Monero binaries, and save the page as `binaryfate.asc` to your home directory.
If the fingerprint **DOES NOT** match, **DO NOT CONTINUE.** Instead delete the file `binaryfate.asc` and go back to [section 2.1](#21-get-signing-key).
