+# Changesets
+
+Hello and welcome! This folder has been automatically generated by `@changesets/cli`, a build tool that works
+with multi-package repos, or single-package repos to help you version and publish your code. You can
+find the full documentation for it [in our repository](https://github.com/changesets/changesets)
+
+We have a quick list of common questions to get you started engaging with this project in
+[our documentation](https://github.com/changesets/changesets/blob/main/docs/common-questions.md)

+## Versioning
+
+This project uses [Changesets](https://github.com/changesets/changesets) to manage versioning and generate changelogs.
+
+A changeset is a markdown file that records project changes, organized into two parts:
+
+1. **YAML Frontmatter**: Specifies the affected packages and the change type (`major`, `minor`, or `patch`).
+2. **Markdown Content**: Describes the changes in more detail.
+
+### Adding a Changeset
+
+Run the following command to create a new changeset:
+
+```bash
+yarn changeset
+```
+
+Then, follow the prompts:
+
+1. Select the change type (`major`, `minor`, `patch`) for each package:
+    - `major` for breaking changes
+    - `minor` for new features
+    - `patch` for bug fixes
+2. Enter a summary of the change, which can be edited later in the generated markdown file.
+
+This will create a new changeset file in the `.changeset` directory. Each changeset filename is a unique, randomly generated string, so do not try to make sense of it.
+
+### Applying Changesets
+
+To apply changesets, use:
+
+```bash
+yarn changeset version
+```
+
+This command performs the following actions:
+
+1. Combines all outstanding changesets per package and applies the most severe change type (`major` > `minor` > `patch`) to update each package version in its `package.json`.
+2. Updates each affected package’s `CHANGELOG.md` with a summary of changes.
+3. Deletes the processed changeset files from the `.changeset` directory.
