When you want to use another package, you first need to add it to your dependencies. Running `yarn add` installs it into your project.
Tags are a way of publishing versions of your package with a label. Users of your package can install that instead of a version number.
Packages in Yarn follow Semantic Versioning, also known as βsemverβ. When you install a new package it will be added with a semver version range.
