 ## Building
 
-Building the repository needs Java <= 11 (The project the project still supports Java 6 and Java 11 dropped support for Java 6 output). We recommend to use an [up-to-data Java 8 installation](https://adoptium.net/en-GB/marketplace/?version=8). The project provides the maven wrapper and therefore no local maven installqation is needed. To build the repository just call `./mvnw verify`.
