Local Development

Step 1: Install the CLI

Install the Fern Command Line Interface (CLI) by running:

npm install -g fern-api

Step 2: Preview docs

The files and folders discussed in the following steps will be inside the fern/ folder in your repository.

fern docs dev

Step 3: Generate your documentation

If you need to resync the live docs and redeploy from local to prod, checkout your git repo locally, pull the latest from the main branch, and run the following command:

fern generate --docs

You will be prompted to log in and connect your GitHub account.

You might also be prompted, yes or no, about if you want to proceed with generating docs and informed that you can choose between using the --preview flag or not. You can choose to use either fern generate --docs or fern generate --docs --preview at this time. This decision is important later, when you are making changes that might affect a production docs environment, but it won't impact your docs project now.

Step 4: Preview your documentation

You can generate documentation previews

Generate previews from CLI

To preview updates to your documentation before publishing changes, run fern generate --docs --preview.
