+## OpenAI
+
+This software supports using OpenAI or other AI service that has an OpenAI comaptible HTTP API to generate commit message. You need configurate the service in `Preference` window.
+
+For `OpenAI`:
+
+* `Server` must be `https://api.openai.com/v1/chat/completions`
+
+For other AI service:
+
+* The `Server` should fill in a URL equivalent to OpenAI's `https://api.openai.com/v1/chat/completions`
+* The `API Key` is optional that depends on the service
