The easiest way to get started using Konik in your project is with a Dependency Management System that is able to access the Maven Central Repository.
Copy the code snippet in the black box to your project’s pom file.
Not using a Dependency Management System? No Problem. Get the zip package containing compiled binaries, source code, and documentation.
If you have a question on how to accomplish a goal with the Konik library or have a different “How to do X” question, please check if a similar question has been asked before. If this is not the case, then you can create a new question. We closely monitor the Konik tags and will answer all of your questions.
Found a bug? The fastest way to get it fixed is to create a ticket on GitHub. You can also see if a similar ticket already exists and comment on that. We always try our best to provide a fix for the next release.
The ticketing system is also a perfect place to request a new feature.
