-*PRNGine* is a pseudo-random number generator library for sequential and parallel [Monte Carlo simulations](https://de.wikipedia.org/wiki/Monte-Carlo-Simulation). It has been designed to work smoothly with the [Jenetics](http://jenetics.io) GA library, but it has no dependency to it. All PRNG implementations of this library extends the Java [Random](http://docs.oracle.com/javase/8/docs/api/java/util/Random.html) class, which makes it easily usable in other projects. *The PRNGs are* **not** *cryptographically strong RNGs.*

In just three XORs and three shifts (generally fast operations) it produces a full period of 2<sup>32</sup> - 1 on 32 bits. (The missing value is zero, which perpetuates itself and must be avoided.)

 ## Requirements
 
-### Runtime
-*  **JRE 8**: Java runtime version 8 is needed for using the library.
-
-### Build time
-*  **JDK 8**: The Java [JDK 8](http://www.oracle.com/technetwork/java/javase/downloads/index.html) must be installed.
-*  **Gradle 3.x**: [Gradle](http://www.gradle.org/) is used for building the library. (Gradle is download automatically, if you are using the Gradle Wrapper script `./gradlew`, located in the base directory, for building the library.)
-*  **TestNG 6.10**: PRNGine uses [TestNG](http://testng.org/doc/index.html) framework for unit tests.
+* **JRE 8**: Java runtime version 8 is needed for using the library.
