Mintlify Docs

Every documentation site requires a docs.json file that contains the core configuration settings. This file controls everything from styling and navigation to integrations and analytics.

If you’re currently using the legacy mint.json configuration file, please update the CLI:

npm i -g mintlify@latest

And run the new upgrade command in your docs repository:

mintlify upgrade

This will generate a docs.json based off of your mint.json. Then, please delete the mint.json file from your repository.

Best Practices

When configuring your docs.json file, consider these best practices:

Keep the configuration organized by grouping related settings together
Use meaningful names for groups and pages in your navigation structure
Provide complete paths for all assets (logos, favicons, etc.)
Test your configuration in both light and dark modes
Verify all external links and integrations are correctly configured
Use appropriate color contrasts for accessibility
Configure SEO settings for better search engine visibility

Validation

The docs.json file is validated against a JSON schema to ensure proper configuration. You can reference the schema by including:

{
  "$schema": "https://mintlify.com/docs.json"
}

`mint.json` (Legacy)

Documentation for the legacy `mint.json` config file
