-HOTP - PHP Based HMAC One Time Passwords
-========================================
+# HOTP - PHP Based HMAC One Time Passwords
 
 **What is HOTP**:
 HOTP is a class that simplifies One Time Password systems for PHP Authentication. The HOTP/TOTP Algorithms have been around for a bit, so this is a straightforward class to meet the test vector requirements.
 
 **What works with HOTP/TOTP**:
 It's been tested to the test vectors, and I've verified the time-sync hashes against the following:
 
-* Android: Mobile-OTP
-* iPhone: OATH Token
+- Android: Mobile-OTP
+- iPhone: OATH Token
 
 **Why would I use this**:
 Who wouldn't love a simple drop-in class for HMAC Based One Time Passwords? It's a great extra layer of security (creating two-factor auth) and it's pretty darn zippy.
