The usual approach is to point to the version of your packages.json file on your master branch, so that when you want to release a new version of your package, you push it to a tag and then merge your updated packages.json file to your master branch. With the URL you have submitted (which points specifically to your 0.1 tag), you would need to submit a new pull request whenever you had a new version to release.

Would you like to change this to point to your master branch?
