+# Licensing
+
+The replay packs of this dataset are dual-licensed.
+
+## Research and non-profit use — CC BY-NC-SA 4.0
+
+The packs, their manifest and their certificates are available under the
+[Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License](https://creativecommons.org/licenses/by-nc-sa/4.0/).
+You may download, replay, redistribute and build upon them for research, teaching and any other non-commercial
+purpose, as long as you credit this dataset and its source geometry (the `citation` field of every pack) and
+release what you build upon them under the same terms.
+
+## Commercial use
+
+A commercial licence is available under separately negotiated terms for use that makes money: inside a product,
+a paid service, contract research, or the training of a model that is sold. It lifts the non-commercial and
+share-alike obligations.

+
+## What the licence covers, and what it does not
+
+The licence covers the simulated records in the packs: the walkers' paths, occupancies, wall contacts and field
+samples, their coefficients, and the certificates. The **source geometry** each pack was simulated on keeps its
+own licence, recorded in the pack's `license` field and in the manifest, and this dataset never relicenses it.
+The replay-pack **format** is a separate, openly licensed specification (CC-BY-4.0 text, Apache-2.0 reference code):
+anyone may produce and read packs under their own terms.
+
+Copies of a pack obtained under an earlier licence of this dataset keep that licence; these terms apply from the
+revision that carries this file.
