 ### License and 3rd party code dependencies
 
-Detailed legal, license, and IP information is [here](https://github.com/BinomialLLC/basis_universal/wiki/Legal-IP-License-Information). Basis Universal itself uses the Apache 2.0 licenses, but it utilizes some zlib and optional BSD code (Zstandard). The supported texture formats are [open Khronos Group standards](https://www.khronos.org/registry/DataFormat/specs/1.1/dataformat.1.1.html).

 All C/C++ code dependencies are present inside the Basis Universal repo itself to simplify building.
 
-The stand-alone transcoder (in the "transcoder" directory) is a single .cpp source file library which has no 3rd party code dependencies apart from zstd/zstddeclib.c, which is optional. (It's only used for decompressing UASTC KTX2 files that use Zstandard.)
-
-The encoder uses [lodepng](https://lodev.org/lodepng/) for loading and saving PNG images, which is Copyright (c) 2005-2019 Lode Vandevenne. It uses the zlib license. It also uses [apg_bmp](https://github.com/capnramses/apg/tree/master/apg_bmp) for loading BMP images, which is Copyright 2019 Anton Gerdelan. It uses the Apache 2.0 license.
-
-The encoder uses [tcuAstcUtil.cpp](https://chromium.googlesource.com/external/deqp/+/refs/heads/master/framework/common/tcuAstcUtil.cpp), from the [Android drawElements Quality Program (deqp) Testing Suite](https://source.android.com/devices/graphics/deqp-testing), for unpacking the transcoder's ASTC output for testing/validation purposes. This code is Copyright 2016 The Android Open Source Project, and uses the Apache 2.0 license. We have modified the code so it has no external dependencies, and disabled HDR support.
-
-The encoder optionally uses Zstandard's single source file compressor (in zstd/zstd.c) to support compressing supercompressed KTX2 files.
