+# Licensing and attribution
+
+## Website implementation and effective revision
+
+The original ASP.NET/Blazor website implementation, tests, and build and
+configuration code are offered under the [MIT license](LICENSE.txt), beginning
+with the revision that introduces this license change. This includes the
+implementation as distributed in that revision and subsequent changes to it.
+Earlier revisions retain their existing licenses. No previously granted
+Creative Commons permissions are revoked, and this change does not relicense
+third-party works or documentation adaptations under MIT.
+
+Copyright in contributions remains with their respective holders. The
+maintainer has confirmed authorization for the original website code and written
+relicensing consent from Decryptedchaos for their UI contributions.
+
+## Documentation and media
+
+`Redot-Documentation/docs/` is excluded from the website MIT grant. Unless a
+more specific notice applies, its content is licensed under Creative Commons
+Attribution 3.0 Unported ([CC BY 3.0](https://creativecommons.org/licenses/by/3.0/)).
+The original, complete license text is preserved in
+[docs/LICENSE.txt](Redot-Documentation/docs/LICENSE.txt).
+
+Attribution: **the Redot community, modified from an original work by Juan
+Linietsky, Ariel Manzur and the Godot community**. The original work is
+[Godot Engine documentation](https://docs.godotengine.org/), whose
+[source repository](https://github.com/godotengine/godot-docs) supplies the
+upstream licensing notice. See also [GODOT_AUTHORS.md](GODOT_AUTHORS.md) and
+[REDOT_AUTHORS.md](REDOT_AUTHORS.md); these documentation attribution records
+remain under CC BY 3.0 and are not included in the website MIT grant.
+
+Redot adapted this documentation for its engine and converted its format from
+Sphinx/reStructuredText to MDX for Docusaurus, then to Markdown rendered by
+ASP.NET/Blazor. Further edits are recorded in repository history. This
+attribution does not imply endorsement by the original authors.
+
+Images and videos **anywhere** under `Redot-Documentation/wwwroot/` are also
+excluded from the website MIT grant, including `img/`, `video/`, `Icons/`,
+`docs_logo.svg`, and `favicon.png`. Media imported from the documentation retains
+CC BY 3.0 unless otherwise noted; separately licensed assets retain their own
+terms. Existing credits in pages, captions, SVG metadata, and adjacent notices
+must be preserved. The exclusion itself does not grant a new license to an
+asset or resolve missing provenance. See
+[the media notice](Redot-Documentation/wwwroot/MEDIA-LICENSES.txt).
+
+## Engine class reference
+
+The class reference is generated from `doc/classes/*.xml` and
+`modules/*/doc_classes/*.xml` in
+[Redot Engine](https://github.com/Redot-Engine/redot-engine), including copies
+stored in the configurable class-documentation cache. It is separate from the
+CC-licensed manual and retains the upstream MIT license:
+
+- Copyright (c) 2024-present Redot Engine contributors (see upstream REDOT_AUTHORS.md).
+- Copyright (c) 2014-present Godot Engine contributors (see upstream AUTHORS.md).
+- Copyright (c) 2007-2014 Juan Linietsky, Ariel Manzur.
+
+The [full upstream notice](Redot-Documentation/wwwroot/licenses/REDOT-ENGINE-MIT.txt)
+is bundled with the site. Upstream author lists are available in the
+[Redot](https://github.com/Redot-Engine/redot-engine/blob/master/REDOT_AUTHORS.md)
+and [Godot](https://github.com/Redot-Engine/redot-engine/blob/master/AUTHORS.md)
+files in that repository. Preserve any more specific source notices. If the
+class source is changed to another repository, review and update its attribution
+and license notices before distributing the resulting reference.
+
+## Third-party software and assets
+
+The website MIT grant does not replace any dependency's license.

+## Contributions
+
+Contribute website implementation changes under MIT; contribute manual changes
+under CC BY 3.0 unless the affected material has a more specific license. New
+media must include its source, author, license, and any modification notice in
+the relevant page or an adjacent notice. Preserve third-party notices and do
+not assume that an asset becomes MIT merely because it is used by the website.
