    It's very helpful when writing documentation to have specific questions like
    "how do I default a subsystem logger to off?" in mind. This helps us ensure

+# Terraform Documentation
+
+This directory contains the portions of [the Terraform website][terraform.io] that pertain to the Terraform Plugin Log.
+
+The files in this directory are intended to be used in conjunction with
+[the `terraform-website` repository](https://github.com/hashicorp/terraform-website), which brings all of the
+different documentation sources together and contains the scripts for testing and building the site as
+a whole.
+
+## Updating Sidebar Navigation
+
+You must update the sidebar navigation for the `terraform-plugin-log` documentation any time that you add or delete a documentation page. The website builds the sidebar navigation menu from the [nav-data] JSON file. For more details about how to update this file, refer to https://github.com/hashicorp/terraform-website#editing-navigation-sidebars.
+
+## Adding Redirects
+
+You must add a redirect when you move, rename, or delete documentation pages. Refer to https://github.com/hashicorp/terraform-website#redirects for details.
+
+## Previewing Changes
+
+You should preview your changes locally to ensure that the content is rendering properly before you create a pull request. The build includes content from this repository and the [`terraform-website`](https://github.com/hashicorp/terraform-website/) repository, allowing you to preview the entire Terraform documentation site.
+
+To preview your content, complete the following steps:
+
+**Set Up Local Environment**
+
+1. [Install Docker](https://docs.docker.com/get-docker/).
+1. Restart your terminal or command line session.
+
+**Launch Site Locally**
+
+1. Navigate into your local `terraform-plugin-log` top-level directory and run `make website`.
+1. Open `http://localhost:3000` in your web browser. While the preview is running, you can edit pages and Next.js will automatically rebuild them.
+1. When you're done with the preview, press `ctrl-C` in your terminal to stop the server.
+
+## Deployment
+
+The website reads content from release tags to generate documentation for all versions of `terraform-plugin-log` documentation. Changes merged into `main` will be included in the documentation for the next product release.
+
+You cannot edit documentation for past versions of `terraform-plugin-log` on the site. Documentation is an artifact of a product release. We push docs fixes forward for the next release, rather than retroactively fixing older versions.
