+V.   Known Issues
+VI.  Frequently Asked Questions
+--------------------------------------------------------------------------------
+
+I.   Introduction
+--------------------------------------------------------------------------------
+
+This is our first alpha release of our new Texture Tools. The main highlights of 
+this release are support for all DX10 texture formats, higher speed and improved
+compression quality.
+
+In addition to that it also comes with a hardware accelerated compressor that 
+uses CUDA to compress blocks in parallel on the GPU and runs around 10 times 
+faster than the CPU counterpart.
+
+You can obtain CUDA from our developer site at:
+
+http://developer.nvidia.com/object/cuda.html
+
+The source code of the Texture Tools is being released under the terms of 
+the MIT license.
+
+
+II.  Contents
+--------------------------------------------------------------------------------
+
+This release contains only the source code of the texture compression library
+and an example commandline application that shows its use.
+
+
+III. Compilation Instructions
+--------------------------------------------------------------------------------
+
+The compression library and the example can be compiled with Visual Studio 8 on 
+Windows using the following solution file:
+
+project\vc8\nvtt.sln
+
+On most other platforms you can also use cmake. For more information about 
+cmake, visit:
+
+http://www.cmake.org/
+
+On unix systems you can use the standard build procedure (assuming cmake is 
+installed on your system):
+
+$ ./configure
+$ make
+$ sudo make install
+
+
+IV.  Using NVIDIA Texture Tools
+--------------------------------------------------------------------------------
+
+To use the NVIDIA Texture Tools in your own applications you just have to
+include the following header file:
+
+src/nvimage/nvtt/nvtt.h
+
+And include the nvtt library in your projects. 
+
+The following file contains a simple example that shows how to use the library:
+
+src/nvimage/nvtt/compress.cpp
+
+The usage of the commandline tool is the following:
+
+$ nvcompress [options] infile [outfile]
+
+where 'infile' is and TGA, PNG, PSD, DDS or JPG file, 'outfile' is a DDS file
+and 'options' is one or more of the following:
+
+Input options:
+  -color   	The input image is a color map (default).
+  -normal  	The input image is a normal map.
+  -tonormal	Convert input to normal map.
+  -clamp   	Clamp wrapping mode (default).
+  -repeat  	Repeat wrapping mode.
+  -nomips  	Disable mipmap generation.
+
+Compression options:
+  -fast    	Fast compression.
+  -nocuda  	Do not use cuda compressor.
+  -rgb     	RGBA format
+  -bc1     	BC1 format (DXT1)
+  -bc2     	BC2 format (DXT3)
+  -bc3     	BC3 format (DXT5)
+  -bc3n    	BC3 normal map format (DXT5n/RXGB)
+  -bc4     	BC4 format (ATI1)
+  -bc5     	BC5 format (3Dc/ATI2)
+
+In order to run the compiled example on a PC that doesn't have Microsoft Visual 
+Studio 2003 installed, you will have to install the Microsoft Visual Studio 2003
+redistributable package that you can download at:
+
+http://go.microsoft.com/fwlink/?linkid=65127&clcid=0x409
+
+
+V.   Known Issues
+--------------------------------------------------------------------------------
+
+None so far. Please send suggestions and bug reports to:
+
+TextureTools@nvidia.com
+
+or report them at:
+
+http://code.google.com/p/nvidia-texture-tools/issues/list
+
+
+VI.  Frequently Asked Questions
+--------------------------------------------------------------------------------
+
+- Do the NVIDIA Texture Tools work on OSX?
+It currently compiles and runs properly, but it has not been tested extensively.
+In particular there may be endiannes errors in the code.
+
+
+- Do the NVIDIA Texture Tools work on Linux?
+Yes.
+
+
+- Do the NVIDIA Texture Tools work on Vista?
+Yes, but note that CUDA is not supported on Vista yet, so the tool is not hardware 
+accelerated.
+
+
+- Is CUDA required?
+No. The Visual Studio solution file contains a configuration that allows you
+to compile the texture tools without CUDA support. The cmake scripts automatically
+detect the CUDA installation and use it only when available.
+
+
+- Where can I get CUDA?
+http://developer.nvidia.com/object/cuda.html
+
+
+- Why is feature XYZ not supported?
+In order to keep the code small and reduce maintenance costs we have limited the 
+features available in our new texture tools. We also have open sourced the code, so
+that people can modify it and add their own favourite features.
+
+
+- Can I use the NVIDIA Texture Tools in my commercial application?
+Yes, the NVIDIA Texture Tools are licensed under the MIT license.
+
+
+- Can I use the NVIDIA Texture Tools in my GPL application?
+Yes, the MIT license is compatible with the GPL and LGPL licenses.

-The NVIDIA Texture Tools is a collection of image processing and texture 
-manipulation tools, designed to be integrated in game tools and asset 
-processing pipelines.
-
-The primary features of the library are mipmap and normal map generation, format 
-conversion, and DXT compression.
-
-
-### How to build (Windows)
-
-Use the provided Visual Studio 2017 solution `project/vc2017/thekla.sln`.
-
-
-### How to build (Linux/OSX)
-
-Use [cmake](http://www.cmake.org/) and the provided configure script:
-
-```bash
-$ ./configure
-$ make
-$ sudo make install
-```
-
-
-### Using NVIDIA Texture Tools
-
-To use the NVIDIA Texture Tools in your own applications you just have to
-include the following header file:
-
-[src/nvtt/nvtt.h](https://github.com/castano/nvidia-texture-tools/blob/master/src/nvtt/nvtt.h)
-
-And include the nvtt library in your projects.
