diceypass is a shell script, so drop it somehwere and make sure it's added to your $PATH. Or use this nifty one-liner:
sudo sh -c "curl https://raw.githubusercontent.com/michaelhue/diceypass/master/diceypass -o /usr/local/bin/diceypass && chmod +x /usr/local/bin/diceypass"

hurst bin mad kid myel sinh no budge

diceypass 6 3

See diceypass --help for a quick reminder.
Generate a TXT-File with 20 passphrases:
diceypass 6 20 > passphrases.txt
Use your own word list:
export DICEYPASS_WORDS="foo bar baz"
diceypass
baz foo bar bar foo bar
Send a passphrase directly to clipboard (on OS X):
diceypass 8 | pbcopy
Secure Diceware passphrases should not be generated with a computer. If you need high-security passphrases, please don't use this script.
However I found that using a computer-generated Diceware passphrase for low-security applications is still better than your average password. diceypass uses /dev/urandom to randomly select words from the list.
Check the official FAQ if you have questions about Diceware.
