In late 2016 Mojang announced that the bedrock edition of Minecraft would be supporting mods through an add-on system. These Add-Ons were created with JSON and could modify the way Minecraft worked. I was constantly asked to create a tutorial in Minecraft modding and this seemed like a great way to do it.
I created a website in which anyone could make Minecraft add-ons using a Blockly based programming enviroment. To send the mod to someones device we generated QR codes with a link to the mod, and when opened it would install it to your Minecraft game. This system worked great and we even taught a class on it.
The website has since been shutdown, and just redirects back to this post, but one day it will return. MinelyMod
