Mintlify can use an existing GitHub repository as read-only context when it generates your documentation. Use this workflow when your product or code lives in one repository and your documentation should live in another.
Mintlify reads your source repository but does not write to it. Mintlify writes generated pages into your documentation workspace, which you can review and publish from the web editor.
## Before you begin
- Make sure you can access the GitHub repository that contains the product or code you want to document.
- Connect a documentation repository during onboarding, or let Mintlify create a documentation repository for you.
- If the source repository is private, be ready to authorize Mintlify's GitHub App when onboarding asks for access.
## Generate documentation from a repository
1. Open [Mintlify onboarding](https://mintlify.com/start).
1. Add the URL of the GitHub repository that contains your source material. You can add more than one source repository.
1. If Mintlify cannot access a private repository, click **Authorize** and complete the GitHub authorization flow. Public repositories can be used as read-only sources without write access.
1. Click **Deploy** to start generation.
The import step also accepts an existing website as source material. Add a website URL instead of a repository URL when you want Mintlify to use published content as context.
The onboarding flow also attempts to find brand context for the generated site. Mintlify checks the domain from the first source URL, then the homepage of a connected GitHub repository, and finally the company name. When brand data is available, the generation agent uses its colors for the `docs.json` primary, light, and dark colors and selects suitable logo and favicon URLs. Brand lookup does not block generation. If no brand data is found, generation continues without these assets.
## Review generated pages
The generated documentation uses the following workflow:
1. Mintlify reads the source repositories as research context.
1. Mintlify writes documentation pages to the writable documentation workspace.
1. New pages appear in the editor navigation as they are written. Mintlify creates sidebar groups from the page path when a matching group does not exist.
1. Mintlify completes the navigation configuration after the pages are written. The final `docs.json` controls the page order and sidebar structure.
Every generated page needs complete YAML frontmatter. During generation, the `title`, `sidebarTitle`, and `description` values in the frontmatter synchronize with the page's navigation metadata when the generation agent writes or edits the page.
```mdx
---
title: "Authenticate API requests"
sidebarTitle: "Authentication"
description: "Learn how to authenticate requests to the API."
---
Explain how readers authenticate their requests.
```
Use `title` for the page title, `sidebarTitle` for a shorter navigation label, and `description` for the page description. If a field is omitted, Mintlify preserves the existing navigation value. If a page has no useful navigation title, Mintlify derives one from the page path.
## Publish your documentation
Open the generated site in the [web editor](/editor/index) to review the pages, navigation, and frontmatter. When your changes are ready, click **Publish**. You can then continue editing with the [web editor](/editor/pages) or your connected Git repository.
For a manual setup without source-repository generation, see the [quickstart](/quickstart).
