-## Usage (ChatGPTAPI)
+## Usage
+
+You need to pick between two methods:
+
+| Method                      | Free?  | Robust?  | Quality?          |
+| --------------------------- | ------ | -------- | ----------------- |
+| `ChatGPTAPI`                | ❌ No  | ✅ Yes   | ☑️ Mimics ChatGPT |
+| `ChatGPTUnofficialProxyAPI` | ✅ Yes | ☑️ Maybe | ✅ Real ChatGPT   |
+
+1. `ChatGPTAPI` - Uses `text-davinci-003` to mimic ChatGPT via the official OpenAI completions API (most robust approach, but it's not free and doesn't use a model fine-tuned for chat). You can override the model, completion params, and prompt to fully customize your bot.
+
+2. `ChatGPTUnofficialProxyAPI` - Uses an unofficial proxy server to access ChatGPT's backend API in a way that circumvents Cloudflare (uses the real ChatGPT and is pretty lightweight, but relies on a third-party server and is rate-limited)
+
+### Usage - ChatGPTAPI
 
 Sign up for an [OpenAI API key](https://platform.openai.com/overview) and store it in your environment.
