Prerequisites

A full build of NSubstitute, including document/website generation and packaging, requires the following (in addition to .NET 4.0 development tools):

• Git. Mysys git for Windows works well. Git will need to be on your path to work with the rake script that builds the project.
• Ruby 1.9+. Using RubyInstaller for Windows is probably easiest. This will let you use the rake script to build and test the project.
• [Optional] To build the documentation as well, you'll need the RubyInstaller DevKit (see wiki for details) and bundler. Running bundle install will then fetch the required dependencies. You can get away without this if you don't need to build and test the documentation.

Note: If you have problems with rake and Ruby 1.9.2, see this StackOverflow answer on removing the rake gem and instead using the bundled version of rake.
