+## How it works
 
-We use headless Chromium via [Playwright](https://playwright.dev), so **you still need to have access to ChatGPT** — it just makes things much easier to access programatically.
+We use headless Chromium via [Playwright](https://playwright.dev) to automate the webapp, so **you still need to have access to ChatGPT**. It just makes building API-like integrations much easier.
 
 Chromium will be opened in non-headless mode by default, which is important because the first time you run `ChatGPTAPI.init()`, you'll need to log in manually. We launch Chromium with a persistent context, however, so you shouldn't need to keep re-logging in after the first time.
 
+> **Note**
+> We'll replace headless chrome with the official API once it's released.
