-#### Stability
+### Stability
 
 As players and administrators ourselves, we take great care into the stability of our core. Other projects focus on the development side of things and tend to forget that users want stability above everything else.
 
 Hence why nobody is allowed to push commits directly to the core. All changes are reviewed and tested before they get to the `master` branch which means we need as many testers as possible to avoid stalling issues.
 
-#### Authenticity
+### Authenticity
 
 Fixing and implementing missing blizzlike content is one of our priorities, and we can boast to offer the most content-complete open-source emulator.
