+Files unique to this repository generally fall under the Apache 2.0 license
+with copyright holders including Mark Callow, the KTX-Software author; The
+Khronos Group Inc., which has supported KTX development; and other
+contributors to the KTX project.

+Because KTX-Software incorporates material and contributions from many other
+projects, which often have their own licenses, there are many other licenses
+in use in this repository. While there are many licenses in this repository,
+with rare exceptions all are open source licenses that we believe to be
+mutually compatible.
+
+The complete text of each of the licenses used in this repository is found
+in LICENSES/*.txt . Additionally, we have updated the repository to pass the
+REUSE compliance checker tool (see https://reuse.software/). REUSE verifies
+that every file in a git repository either incorporates a license, or that
+the license is present in auxiliary files such as .reuse/dep5 . To obtain a
+bill of materials for the repository identifying the license for each file,
+install the REUSE tool and run
+
+    reuse spdx
+
+inside the repository.
+
+## Special Cases
+
+The file lib/etcdec.cxx is not open source. It is made available under the
+terms of an Ericsson license, found in the file itself.
