 # Getting Catch
 
-The simplest way to get Catch is to download the single header version from [http://builds.catch-lib.net](http://builds.catch-lib.net). Don't be put off by the word "builds" there. The single header is generated by merging a set of individual headers but it is still just normal source code in a header file.
+The simplest way to get Catch is to download the latest [single header version](https://raw.githubusercontent.com/philsquared/Catch/master/single_include/catch.hpp). The single header is generated by merging a set of individual headers but it is still just normal source code in a header file.
 
 The full source for Catch, including test projects, documentation, and other things, is hosted on GitHub. [http://catch-lib.net](http://catch-lib.net) will redirect you there.
