+#### Generating Conventional Commits
+
+If you'd like to generate [Conventional Commits](https://conventionalcommits.org/), you can use the `--type` flag followed by `conventional`. This will prompt `aicommits` to format the commit message according to the Conventional Commits specification:
+
+```sh
+aicommits --type conventional # or -t conventional
+```
+
+This feature can be useful if your project follows the Conventional Commits standard or if you're using tools that rely on this commit format.
+
 ### Git hook
 
 You can also integrate _aicommits_ with Git via the [`prepare-commit-msg`](https://git-scm.com/docs/githooks#_prepare_commit_msg) hook. This lets you use Git like you normally would, and edit the commit message before committing.

 ## How it works
 
 This CLI tool runs `git diff` to grab all your latest code changes, sends them to OpenAI's GPT-3, then returns the AI generated commit message.
