why are there no instructions on how to use 6.0 alpha
Look it up. If you search hard enough, you'll find it
Its in alpha i.e Not complete yet there is no instructions
it's alpha, so it has probably not been implemented yet, or atleast not implemented on most things, as some items do have a description on how they work, like the plastanium conveyors
because the features aren't complete, so, a tutorial will be outdated too fast and be a time wasting
