 # Rscons
 
-![rscons logo](img/rscons_logo_1000.png)
-
 Rscons (https://github.com/holtrop/rscons) is an open-source build system
 for developers.
-It supports the following features:
 
-  * multi-threaded job execution
+Rscons is written in Ruby, and is inspired by [SCons](https://scons.org/) and [waf](https://waf.io/).
-  * auto-configuration
-  * built-in builders for several common operations
-  * out-of-the-box support for Assembly, C, C++, D, and LLVM
-  * extensibility for other languages or custom builders
-  * compatible with Windows, Linux, OS X, and FreeBSD
-  * colorized output with build progress
-  * build hooks
-  * user-defined tasks with dependencies and custom parameters
-  * build variants
-
-At its core, Rscons is mainly an engine to:
-
-  * determine the proper order to perform build steps,
-  * determine whether each build target is up to date or in need of rebuild, and
-  * schedule those build steps across multiple threads as efficiently as possible.
-
-Along the way, Rscons provides a concise syntax for specifying common types of
-build steps, but also provides an extensible framework for performing
-custom build operations as well.
-
-Rscons takes inspiration from:
-
-  * [SCons](https://scons.org/)
-  * [waf](https://waf.io/)
-  * [rake](https://github.com/ruby/rake)
-  * [CMake](https://cmake.org/)
-  * [Autoconf](https://www.gnu.org/software/autoconf/)
-
-Rscons is written in Ruby.
-The only requirement to run Rscons is that the system has a Ruby interpreter
-installed.
 
 See [https://holtrop.github.io/rscons/index.html](https://holtrop.github.io/rscons/index.html) for User Guide and Installation instructions.
