Goldtree is a C# CLI tool for USB installations with Goldleaf. Currently it's only available for Windows systems, but it simplifies the process.
USB communication is slightly different from Tinfoil's one, so Tinfoil's old Python script, AluminumFoil nor other tools won't work properly.
Goldtree will ask you to choose a NSP after establishing connection with Goldleaf, and it will be received and installed by Goldleaf.
