"no version" -> you need to create tags on GitHub in order for Nimble to treat it as a version
"install test failing": As you can see from [https://nimble.directory/ci/badges/diff/nimdevel/output.html](https://nimble.directory/ci/badges/diff/nimdevel/output.html) Nimble thinks the repository uses hg rather than git, and this is because of an incorrect entry in: [https://github.com/nim-lang/packages/blob/master/packages.json#L15682](https://github.com/nim-lang/packages/blob/master/packages.json#L15682)
