The goal of the Package Metadata Interoperability Collab Space is to improve how JavaScript developers define their packages across the ecosystem. The group is currently working to better understand package.json and how developers use it to define their projects.
This PR moves https://github.com/openjs-foundation/package-metadata-interoperability-collab-space/issues/15 into a file in the repo. The file in this PR is almost identical to the top post of that issue, with the addition of headings and intro sentence and some links at the end.
