+## Changesets and publishing packages
+
+> This monorepo is set up with changesets versioning tool. See their [github repository](https://github.com/changesets/changesets) to learn more.
+
+### What are Changesets?
+
+Changesets are files that describe the intention of a contributor to bump a version of the package according to their changes. Changeset file holds two key bits of information: a version type (following semver), and change information to be added to a changelog.
+
+### Adding changesets
+
+In the root directory of the repo, run:
+
+```
+npx changeset
+```
+
+Select the package that has been changed, the semver version that should be bumped with it and a description of your changes. Please make sure to add the most accurate but also concise information.
+
+To learn about semantic versioning standards see [this semver doc page](https://semver.org/).
