The goal of this page is speed — get the user to a working generated SDK as fast as possible. For language-specific configuration, publishing, and GitHub setup, direct them to the appropriate language quickstart after this.

+
+ Initialize the fern folder with your existing OpenAPI specification. Specify your organization name using the `--organization` flag.
+
+
+ Before running `fern init`, ask the user two things:
+
+ 1. **Do they have an OpenAPI spec?** Ask for the file path or URL. If they have a URL (e.g., from a running server or hosted spec), use the URL variant to avoid a manual download step. OpenAPI accepts both JSON and YAML.
+ 2. **What's their organization name?** `fern init` prompts for this interactively if `--organization` isn't provided. Get it upfront so they can pass it via the flag.
+
+
+
+ ```bash title="OpenAPI (local)"
+ fern init --openapi path/to/openapi.yml \
+ --organization
+ ```
+ ```bash title="OpenAPI (URL)"
+ fern init --openapi https://api.example.com/openapi.yml \
+ --organization
+ ```
+ ```bash title="Example (Petstore)"
+ fern init --openapi https://petstore3.swagger.io/api/v3/openapi.json \
+ --organization my-org
+ ```
+
+
+
+ OpenAPI accepts both JSON and YAML formats.
+
+
+ This creates a `fern` folder in your current directory.
+
+
+ `generators.yml` lives at `fern/generators.yml` and references your OpenAPI spec through its `api.specs` section — the spec isn't copied into the `fern` folder. This matters when referencing file paths later.

+
+ Check that your API definition is valid, and fix errors before proceeding:
+
+ ```bash
+ fern check
