You should use Paket's github dependency to include the YoLo.fs file into your project. https://fsprojects.github.io/Paket/github-dependencies.html Or in short: github haf/YoLo YoLo.fs Because it's licensed under the wtf-you-want license you can use this code in any way you want. Run this when you want to adapt YoLo to your project: ruby -pi.bak -e "gsub(/module internal YoLo/, 'module internal YOURNAMESPACE.YoLo')" paket-files/haf/YoLo/YoLo.fs If you're using Rakefile: task :yolo do system 'ruby -pi.bak -e "gsub(/module internal YoLo/, 'module internal YOURNAMESPACE.YoLo')" paket-files/haf/YoLo/YoLo.fs' unless Albacore.windows? end Also, if you want to compile out-of-the box you can just add paket-files/haf/YoLo.fs to your SCM system.
