**The moeru-ai/airi repository is released under the MIT License, a permissive open-source license that allows free use, modification, and distribution for both personal and commercial projects, provided the original copyright notice and license text are preserved.**

The moeru-ai/airi project is a comprehensive monorepo spanning Electron desktop applications, Vue-based web interfaces, mobile platforms, and shared TypeScript packages. Understanding the moeru-ai/airi license terms is essential for developers integrating these components into their own applications or contributing to the ecosystem.

## MIT License Overview for moeru-ai/airi

The MIT License governing moeru-ai/airi is a short, permissive software license that places minimal restrictions on reuse. According to the `LICENSE` file in the repository root, the license grants explicit permission to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software.

### Key Permissions and Requirements

When working with moeru-ai/airi code, the MIT License provides these specific rights and obligations:

- **Unrestricted Use**: You may use the code in personal, academic, or commercial projects without limitation on the type of deployment.
- **Modification Rights**: You are free to fork, alter, and extend the codebase to suit your specific requirements.
- **Distribution**: You can redistribute the original or modified versions in source or compiled form.
- **Attribution Requirement**: All copies or substantial portions must include the original copyright notice and the full license text found in the `LICENSE` file.
- **No Warranty**: The software is provided "as is" without warranty of any kind, and the authors bear no liability for damages arising from its use.

### Warranty Disclaimer

As stated in the root `LICENSE` file, the moeru-ai/airi authors explicitly disclaim all warranties, including but not limited to implied warranties of merchantability and fitness for a particular purpose. This standard MIT language protects contributors while allowing users to evaluate and deploy the software at their own discretion.

## License File Locations in the Repository

The moeru-ai/airi monorepo maintains consistent MIT licensing across all packages, with license files located at multiple levels to ensure clarity for users of specific components.

### Root License

The primary `LICENSE` file in the repository root governs the entire project and serves as the default license for all code unless otherwise specified.

### Package-Specific Licenses

Individual packages within the monorepo contain their own `LICENSE` files mirroring the MIT terms:

- **`packages/font-departure-mono/LICENSE`**: Covers the departure mono font package
- **`packages/ccc/LICENSE`**: Governs the `ccc` package components
- **`integrations/vscode/vscode-airi/LICENSE`**: Applies to the Visual Studio Code extension integration

These distributed license files ensure that users importing specific packages have immediate access to the licensing terms without navigating to the repository root.

## Compliance Guidelines for Developers

When integrating moeru-ai/airi code into your projects or contributing new files to the repository, follow these specific practices to maintain MIT License compliance.

### Adding License Headers to New Files

For contributors adding new source files to the moeru-ai/airi repository, include a standard header referencing the MIT License and SPDX identifier:

```typescript
/**
 * Copyright (c) 2024-Present Neko Ayaka
 *
 * SPDX-License-Identifier: MIT
 *
 * This file is part of the AIRI project and is licensed under the MIT License.
 * See the LICENSE file in the repository root for full terms.
 */

```

The `SPDX-License-Identifier: MIT` tag enables automated license scanning tools to immediately recognize the permissive licensing without parsing the full license text.

### Using AIRI in Your Projects

When incorporating moeru-ai/airi packages into your own applications, you may install them via your package manager and use them without restriction, provided you preserve attribution when redistributing:

```bash

# Install a published package from the AIRI monorepo

pnpm add @proj-airi/stage-ui

```

```typescript
import { useAiriFeature } from '@proj-airi/stage-ui'

// Your proprietary or open-source code can now utilize the feature
useAiriFeature()

```

If you distribute your application containing moeru-ai/airi code (whether in source or binary form), you must include the original copyright notice and MIT License text, typically in a `LICENSE` or `NOTICE` file alongside your own licensing documentation.

- The license requires **preservation of copyright notices** and inclusion of the license text in redistributed copies, but imposes no other restrictions.
- License files are located at the repository root (`LICENSE`) and within individual packages such as `packages/font-departure-mono/LICENSE` and `integrations/vscode/vscode-airi/LICENSE`.
- Contributors should use **SPDX-License-Identifier: MIT** headers in new source files to facilitate automated license detection.
- The MIT License provides **no warranty** and protects authors from liability, making it suitable for both experimental and production deployments.

## Frequently Asked Questions

### Is moeru-ai/airi free for commercial use?

Yes. The MIT License explicitly permits commercial use, including incorporation into proprietary software products and services. You may use, modify, and distribute moeru-ai/airi code in commercial applications without paying royalties or obtaining additional permissions, provided you include the original copyright notice and license text.

### What attribution is required when using moeru-ai/airi code?

You must include the original copyright notice and the full MIT License text in all copies or substantial portions of the software. This is typically accomplished by including the `LICENSE` file from the repository root (or the relevant package directory) in your distribution, or by reproducing the copyright line and license text in your documentation or source code comments.

### Does the MIT license cover all packages in the monorepo?

Yes. The entire moeru-ai/airi monorepo is governed by the MIT License. While the root `LICENSE` file applies to the entire repository, individual packages such as `packages/ccc`, `packages/font-departure-mono`, and `integrations/vscode/vscode-airi` contain their own `LICENSE` files confirming that the same MIT terms apply to those specific components.

### Can I modify and redistribute moeru-ai/airi under a different license?

Yes. The MIT License allows you to modify the code and distribute your modifications under different terms, including proprietary licenses. However, the original moeru-ai/airi code that you incorporated remains under the MIT License, and you must preserve the original copyright notice and license text for those portions. This approach is commonly used when creating derivative works or embedding the code into larger proprietary systems.
