 ## Modifying Sidebar Navigation
 
-Updates to the sidebar navigation of Terraform docs need to be made in the [`terraform-website`](https://github.com/hashicorp/terraform-website/) repository (preferably in a PR also updating the submodule commit). You can read more about how to make modifications to the navigation in the [README for `terraform-website`](https://github.com/hashicorp/terraform-website#editing-navigation-sidebars).
+You must update the the sidebar navigation when you add or delete documentation .mdx files. If you do not update the navigation, the website deploy preview fails.
+
+To update the sidebar navigation, you must edit the appropriate `nav-data.json` file. This repository contains the sidebar navigation files for the following documentation sets:
+- Terraform Language: [`language-nav-data.json`]https://github.com/hashicorp/terraform/blob/main/website/data/language-nav-data.json]
+- Terraform CLI: [`cli-nav-data.json`](https://github.com/hashicorp/terraform/blob/main/website/data/cli-nav-data.json)
+- Introduction to Terraform: [`intro-nav-data.json`](https://github.com/hashicorp/terraform/blob/update-readme/website/data/intro-nav-data.json)
+
+For more details about how to update the sidebar navigation, refer to [Editing Navigation Sidebars](https://github.com/hashicorp/terraform-website#editing-navigation-sidebars) in the `terraform-website` repository.
