You don't have much to do: Add your package here: [https://github.com/nim-lang/Nim/blob/b50ae6817a8cf558eedbee5e405dd68a7d22edd8/testament/important_packages.nim#L6](https://github.com/nim-lang/Nim/blob/b50ae6817a8cf558eedbee5e405dd68a7d22edd8/testament/important_packages.nim#L6)
If it requires a command different from `nimble test` to launch the test suite, add the command string. If there is no test suite, we can test that at least compilation still works, just add `nim c wnim.nim` without the `-r` flag
