---------------------------------------------------------------------------------
-
-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.

+NVIDIA Texture Tools
+====================
+
+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)
+
+Open `project/vc12/thekla.sln` using Visual Studio.
+
+Solutions for previous versions are also available, but they may not be up to date.
+
+
+### 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/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
+
+Detailed documentation of the API can be found at:
