Follow these steps to create a new site using the Gatsby CLI:
This guide assumes that you have some familiarity with the command line, and have Node.js and npm installed locally. Check out nodejs.org for more information. You will need npm v5.2.0 or higher to use the npx command in step 1.
Use the Gatsby CLI and the Doctocat starter to scaffold a new site:
npx gatsby new my-site https://github.com/primer/doctocat-starter
my-site is an arbitrary title — you can pick anything. Running the above command will place the code for your new site in a new directory called “my-site”. If you want to create a new site in an existing repository, be sure to run the gatsby new command from within that repository.
Navigate into the newly created site directory using cd:
cd my-site
Check out the getting started guide for more information about the important files and subdirectories in your new site directory.
Use the develop npm script to start Gatsby's hot-reloading development environment:
npm run develop
To view your site locally, navigate to http://localhost:8000 in your browser. Each page of the site corresponds to a file in the content directory. Navigate to any page then try editing the corresponding MDX file. You should see the page update in real time.
