First release.
Install:
On standard launcher:
Unzip to "%appdata%\.minecraft\blueprints\" folderThere should be file pack.json at "%appdata%\.minecraft\blueprints\MekanismColonies\pack.json"
On Curse Launcher path is different. It's like:
Unzip to "C:\Users\(Your_username)\curseforge\minecraft\Instances\(Your_instance_name)\blueprints\"There should be file pack.json at "C:\Users\(Your_username)\curseforge\minecraft\Instances\(Your_instance_name)\blueprints\MekanismColonies\pack.json"
The correct path depends on launcher and personal settings.
