 * `XOR32ShiftRandom`: This generator was discovered and characterized by George Marsaglia [[Xorshift RNGs](http://www.jstatsoft.org/v08/i14/paper)]. 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.) High and low bits pass Diehard.

 ## 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.
