description: Official Stainless-generated clients in this monorepo and how they relate to the API Reference tab.
---

Official **Rails** client libraries in this monorepo live under **`rails-sdks/`**. They are **generated with [Stainless](https://www.stainless.com/)** from the same HTTP API documented in the **API Reference** tab—open that tab when you need exact paths, headers, bodies, and copy-paste examples in each language.

Always open the **README** in each folder for current versions, environment variable names, and examples.

## How this site is organized

- **Guides** (this tab) — Concepts, onboarding, architecture, and authentication.
- **API Reference** — Generated HTTP reference and SDK snippets for the Rails API (same source as the client libraries).

If this site and a README disagree, trust the **package your team actually publishes** as the source of truth, then open an issue on the spec or generator so everything can be aligned.

## Try code without writing a full app

Use [`rails-sdk-samples/`](https://github.com/railsinfra/rails-sdk-samples): each folder is a small server with Swagger UI. Set **`RAILS_BASE_URL`** and **`RAILS_API_KEY`** in `.env`, then follow [Quick start](/guides/quick-start/index.md) for ports and run commands.
