 A simple [`UniformRandomBitGenerator`](http://en.cppreference.com/w/cpp/concept/UniformRandomBitGenerator) wrapper for the [xoroshiro128+](http://xoroshiro.di.unimi.it/) PRNG.
 
-Features
+## Features
 
 - Compatible with the C++11 `<random>` library.
+  The engine can be plugged into any random number distribution ([`http://en.cppreference.com/w/cpp/concept/RandomNumberDistributionin`](http://en.cppreference.com/w/cpp/concept/RandomNumberDistribution)) in order to obtain a random number.
 
-  Any uniform random bit generator (`UniformRandomBitGenerator`) may be plugged into any random number distribution in order to obtain a random number.
