As per our CONTRIBUTING.md, entries should be sorted in alphabetical order, but this one isn't. Please see the build logs for details of where the entry should be. Note, if you have a username/repo-name project name listed, we use the entire thing, not just the repo-name, as we don't specially support those and always use the entire project name.
