Prerequisites

A full build of NSubstitute, including document/website generation and packaging, requires the following (in addition to .NET 3.5 development tools):

• Git. Mysys git for Windows works well. Git will need to be on your path.
• Ruby 1.9+. Using RubyInstaller for Windows is probably easiest.
• RubyInstaller DevKit (see wiki for details)
• These Ruby gems: rubygems, rake, rspec, shoulda, rsubstitute, jekyll (plus their dependencies)

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.
