Pkg has noticed that your local git repository is not ready to create a pull request.
Best practice is to create a feature branch before you make any changes.
git checkout master
git checkout -b yourfeaturebranch
Then make your changes, including adding relevant test cases in to test/runtests.jl
, and ensure the tests all pass. Then commit our changes before running Pkg.submit("PackageName")
again.
git add .
