A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

Pantheon Documentation

This repository contains the Pantheon documentation as well as the tools to build local test environments.


  • 2023/02: Pantheon Docs is now a Pantheon Front-End site running Gatsby 4.
  • 2019/08: We've relaunched the project using Gatsby for faster development, and much faster page speed.


Our docs are written in Markdown and extended with MDX components. The pages live in source/content. Read CONTRIBUTING for more details on contributing documentation improvements.

Style Guide

Read our Style Guide for our guidelines on how to write documentation.

Local Installation


  • MacOS or Linux system (untested with Bash on Windows)

  • Node.js

  • NVM

  • Gatsby CLI:

    npm install -g gatsby-cli
  • Alternatively, you can use Lando. Use Lando to bypass installing Node.js and the Gatsby CLI on your local machine. Lando requires a Docker version in the - 3.1.99 range.

Mac Steps

This list of steps should work on a Mac with Homebrew:

brew install node
curl -o- | bash
nvm install 18
npm install -g gatsby-cli

Get the Code

Fork and clone this repository:

git clone
cd documentation

Create a GitHub API Token

We use the gatsby-remark-embed-snippet to use files from GitHub in our docs. Before you can build a local development site, you need to provide a GitHub token to the environment:

  1. Log in to GitHub and go to
  2. Click Generate new token.
  3. Give the token a name, expiration, and description.
  4. Select your GitHub user as the resource owner.
  5. For repository access, select Only select repositories and select your fork of this repository.
  6. Under Repository permissions, choose Access: Read-only from the Access dropdown button.
  7. Click Generate token.

GitHub Tokens (classic)

Alternatively, if you'd rather create a classic-style token:

  1. Log in to GitHub and go to

  2. Click Generate new token (classic)

  3. Give the token a name and click the public_repo checkbox, then the Generate Token button at the bottom

  4. Copy the token to your clipboard

  5. In the root documentation directory, create a new file called .env.development and add (replacing $TOKENHASH ):


Install With The Gatsby Cli

From the documentation directory:

npm ci


Still in the documentation directory:

npm start

Use your local browser to navigate to localhost:8000/.

Locally saved updates to docs are automatically refreshed in the browser.

Install With Lando

Alternatively, you can use Lando. The lando start command initiates the app, installs node dependencies, and starts the gatsby develop server for you:

lando start

You can view the local environment at localhost:8000/. Updates to docs are automatically refreshed in the browser.


We include several tools to test that new content doesn't break the documentation. Most of these tests are performed automatically by our continuous integration service, but pull requests created from external contributors aren't included in CI tests. If you want to manually test your branch, you can execute the following tests within the Docker container.

Merge Conflicts

To check for merge conflict messages accidentally committed into the docs, run from scripts.
