 To create new TOTP secret:
 
     require "otp"
 
+    # Create a TOTP instance and new key
     totp = OTP::TOTP.new
     totp.new_secret  # create random secret
+    p totp.password  #=> "123456" (password for the current time)
+
+    # Inspect TOTP parameters
     p totp.secret    #=> "YVMR2G7N4OAXGKFC" (BASE32-formated HMAC key)
     p totp.algorithm #=> "SHA1" (HMAC algorithm; default SHA1)
     p totp.digits    #=> 6 (number of password digits; default 6)
     p totp.period    #=> 30 (time step period in second; default 30)
     p totp.time      #=> nil (UNIX time by Time or Integer; nil for the current time)
-    p totp.password  #=> "123456" (password for the current time)
 
     # Format TOTP URI. Otpauth scheme URLs can be read by OTP::URI.parse.
     totp.issuer = "My Company"
     totp.accountname = "[e-mail]"
