# Overview

> The `navigation` property controls the hierarchy of your documentation.

It can contain one of seven properties:

* `pages`
* `groups`
* `anchors`
* `tabs`
* `dropdowns`
* `versions`
* `languages`

These properties all serve the function of partitioning your content and creating a hierarchy so that it's
easier for your users to navigate through your documentation.

<Note>
  If you're currently using the legacy `mint.json` configuration file, please update the CLI:

  ```sh theme={null}
  npm i -g mintlify@latest
  ```

  And run the new `upgrade` command in your docs repository:

  ```sh theme={null}
  mintlify upgrade
  ```

  This will generate a `docs.json` based off of your `mint.json`. Then, please delete the `mint.json` file from your repository.
</Note>
