 ## Methods
 
-#### setGradient(color1, color2) - sets two or more hex color values. Should always be defined.
+##### setGradient(color1, color2) - sets two or more hex color values. Should always be defined.
 
-#### setMidpoint(n) - sets the number range to n. By default n is 10.
+##### setMidpoint(n) - sets the number range to n. By default n is 10.
 
-#### getArray()  - returns an array of hex colors. Requires no parameters.
