## Development server

You can start a local development server with Docker by running the following command from this (the `website`) directory:

```
docker compose up --build

The development server will be available on http://localhost:3000/ .

Click **Edit this page** at the bottom of any OpenTofu website page to go directly to the associated markdown file in GitHub.

## Modifying Sidebar Navigation

You must update 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:

- OpenTofu Language: [`language-nav-data.json`](https://github.com/opentofu/opentofu/blob/main/website/data/language-nav-data.json)
- OpenTofu CLI: [`cli-nav-data.json`](https://github.com/opentofu/opentofu/blob/main/website/data/cli-nav-data.json)
- Introduction to OpenTofu: [`intro-nav-data.json`](https://github.com/opentofu/opentofu/blob/main/website/data/intro-nav-data.json)
