+## ⚠️ Note for ChatGPT and DeepL
 
-You need to apply an API key on [OpenAI API keys](https://platform.openai.com/account/api-keys).
-And write it to `$XDG_CONFIG_HOME/gtt/gtt.yaml` or `$HOME/.config/gtt/gtt.yaml`.
+ChatGPT and DeepL translations require API keys, which can be obtained from
+[OpenAI API keys](https://platform.openai.com/account/api-keys) and
+[DeepL API signup](https://www.deepl.com/pro-api) pages, respectively. Note
+that only the free API is supported for DeepL currently. Once you have your
+API key add it to `$XDG_CONFIG_HOME/gtt/gtt.yaml` or
+`$HOME/.config/gtt/gtt.yaml`:
 
 ```yaml
 api_key:
-    chatgpt: YOUR_API_KEY # <- Replace with your API Key
+    chatgpt: CHATGPT_API_KEY # <- Replace with your API Key
+    deepl: DEEPL_API_KEY # <- Replace with your API Key
