 Our overall goal with this project is to simplify the encoding and efficient distribution of *portable* LDR and HDR GPU texture, image, and short texture video content in a way that is compatible with any GPU or rendering/graphics API.
 
-The system supports four modes: ETC1S, UASTC LDR 4x4, UASTC HDR 4x4, and three variants of UASTC HDR 6x6 (highest quality, RDO, and intermediate). The C/C++ encoder and transcoder libaries can be compiled to native code or WebAssembly, and all encoder/transcoder features can be accessed from Javascript via a C++ wrapper library which optionally supports [WASM multithreading](https://web.dev/articles/webassembly-threads) for fast encoding in the browser.

 ### Other Features
 
-Both .basis and .KTX2 files support mipmap levels, texture arrays, cubemaps, cubemap arrays, and texture video, in all four modes. Additionally, .basis files support non-uniform texture arrays, where each image in the file can have a different resolution or number of mipmap levels.

 In ETC1S mode, the compressor is able to exploit color and pattern correlations across all the images in the entire file using global endpoint/selector codebooks, so multiple images with mipmaps can be stored efficiently in a single file. The ETC1S mode also supports skip blocks (Conditional Replenishment) for short video sequences, to prevent sending blocks which haven't changed relative to the previous frame.

 WebGL Examples
 --------------
 
-The 'WebGL' directory contains four simple WebGL demos that use the transcoder and compressor compiled to [WASM](https://webassembly.org/) with [emscripten](https://emscripten.org/). These demos are online [here](https://subquantumtech.com/uastchdr2/). See more details in the readme file [here](webgl/README.md).
