# Configuration
Requiem provides sensible defaults but allows customization through configuration files and directory structure.
This chapter covers:
- **[Configuration File](./configuration/config-file.md)** - The `config.toml` format and options
- **[Directory Structure](./configuration/directory-structure.md)** - Organizing requirements on disk
- **[Namespaces](./configuration/namespaces.md)** - Using namespaces for large projects
Proper configuration helps Requiem adapt to your project's needs.
