I'm a teacher and Minecraft noob, and I been playing around with the education edition of ComputerCraft, i.e., ComputerCraftEdu. It uses programmable turtles, but with a more accessible GUI. However, I cannot locate any printed documentation; the URL for the mod's wiki seems to be broken:
I presume this issue may have something to do with the change of the "MinecraftEdu" product to "Minecraft: Education Edition." Presumably, this name change also affected the domain name of the related website, i.e., http://minecraftedu.com currently redirects to https://education.minecraft.net/.
That said, I tried modifying the problematic URL to point to the newer domain, but I came up short. I also tried contacting the distributor of the mod and the mod's developer, but I was unsuccessful.
Does the wiki exist on a new site? Or is there a new path on the new site? Does written documentation exist anywhere else?
