+pr_title_template: "Based on the following git diff, generate 10 pull request title suggestions. Each title should be on a new line, without any numbering or bullet points:\n\n%s"
+```
 
-- **No API key required**: Uses your existing Claude Code authentication
-- **Fast and cost-effective**: Leverages Claude Haiku model
-- **Configurable**: Set custom number of suggestions per provider
+### Per-Repository Configuration
 
-Requirements:
-- Claude Code CLI installed and authenticated
-- Command `claude` available in PATH
+You can override the prompt configuration on a per-repository basis by creating a `.lazycommit.prompts.yaml` file in the root of your git repository. This is useful for projects that require different languages or commit message formats.
