The library should work straight out the box without any crazy setup.
You should aim to use the VoxelVolume or NetworkedVoxelVolume components, if those don't fulfil your needs, look at implementing your own BaseVoxelVolume<T, U>.
You can view examples of how to use the library on this GitHub page, or see the library action on sbox.game.
If you encounter issues with the library, please open an issue, or a pull request to fix said issue.
In your issue (or pull request) describe the problem, and the steps for reproducing said problem.
