Commercial Use Guidance

This file covers commercial-use guidance for the repository’s dual-license model. This file is a repository policy statement and not legal advice.

Book content

Reader-facing book content is licensed under CC BY-NC-SA 4.0. That default license does not grant commercial use of the book prose, figures, or editorial structure.

If you need commercial rights for book content, contact ITDO Inc. at info@itdo.jp. Do not post confidential commercial terms in a public GitHub issue.

Code and reusable technical assets

Code, build files, schemas, automation, site-generation assets, and reusable technical examples are licensed under Apache-2.0. That license already permits commercial use, subject to its own conditions.

Trademarks and third-party assets

Commercial rights to book content do not include trademark rights. Third-party and upstream materials remain subject to their own licenses and notices.

See LICENSE-SCOPE.md, TRADEMARKS.md, and THIRD_PARTY_NOTICES.md for the canonical boundary.
