+Vavr is an object-functional language extension to Java 8 that aims to reduce the number of lines of code and increase code quality.
+It provides persistent collections, functional abstractions for error handling, concurrent programming, pattern matching, and much more.
 
 Vavr fuses the power of object-oriented programming with the elegance and robustness of functional programming.
 The most interesting part is a feature-rich, persistent collection library that smoothly integrates with Java's standard collections.
 
-Because Vavr does not depend on any libraries (other than the JVM) you can easily add it as standalone .jar to your classpath.
