 * Serialize a bool with only one bit
 * Serialize any integer value from [1,64] bits writing only that number of bits to the buffer
 * Serialize signed integer values with [min,max] writing only the required bits to the buffer
-* Serialize floats, doubles, compressed floats, strings, byte arrays, varints, and integers relative to another integer
+* Serialize floats, doubles, compressed floats, strings, byte arrays, and integers relative to another integer
 * Alignment support so you can align your bitstream to a byte boundary whenever you want
 * Template based serialization system so you can write a unified serialize function instead of separate read and write functions
