Changesets allows you to manage version control for your packages by creating a CHANGELOG.md THAT updates after squashing all patches, minors and majors.
To prepare a new repository for changesets, you can find instructions here.
npx changeset will allow you to document a change that you'd like to put under a patch, minor or major.
npx changeset version will collect up all patches, minors and majors and put out a new version within the CHANGELOG.md describing those patches, minor or major changes.
