 For over 30 probability distributions, this library provides:
 
 * Random variable generation
-* Density, Probability and Quantile functions
+* Density, Probability, Survival and Quantile functions
+
+Mathematical functions are tested for high precision and
+RNG tested to correctly fit the distribution
+
+# Installation
+Builds static library with header file, optionally run tests
+```bash
+$ zig build -Doptimize=ReleaseFast
+$ zig build test
+$ zig build correctness -Doptimize=ReleaseFast
