Prerequisites:
  • Node.js version 19 or higher
  • A docs repository with a docs.json file
Follow these steps to install and run Mintlify on your operating system.
1

Install the Mintlify CLI

npm i -g mint
2

Preview locally

Navigate to your docs directory where your docs.json file is located, and run the following command:
mint dev
A local preview of your documentation will be available at http://localhost:3000.

​
Custom ports

By default, Mintlify uses port 3000. You can customize the port Mintlify runs on by using the --port flag. For example, to run Mintlify on port 3333, use this command: 
mint dev --port 3333
If you attempt to run Mintlify on a port that’s already in use, it will use the next available port: 
Port 3000 is already in use. Trying 3001 instead.

​
Mintlify versions

Please note that each CLI release is associated with a specific version of Mintlify. If your local preview does not align with the production version, please update the CLI: 
npm mint update
The CLI can assist with validating links in your documentation. To identify any broken links, use the following command: 
mint broken-links

​
Deployment

If the deployment is successful, you should see the following:

​
Code formatting

We suggest using extensions on your IDE to recognize and format MDX. If you’re a VSCode user, consider the MDX VSCode extension for syntax highlighting, and Prettier for code formatting.
