 ## Option 3: Compiling and installing the git repository
 
 In case you wan't a fresh version of Fort validator, there's this third option. The steps are mostly the same as in [Option 2](#option-2-compiling-and-installing-the-release-tarball), just another dependency (as minimum) must be installed: "git"; and a few steps are included in order to get the source code and generate configuration scripts.
