Start with a crafting recipe you design yourself, then grow it into a full datapack: functions, loot tables, tags and advancements. No mod loader, no install and no admin rights, so you can build it anywhere and drop it into any world.

No install needed: every episode here builds a datapack, which is just a folder of text files. That means no mod loader, no admin rights and no powerful PC, so it works at home and on a school computer. You do need Minecraft Java Edition to test in-game, but you can start in the browser Studio right now.

Ember says: we build in small steps, and each one ends with something you can actually see in the game. A datapack is the friendliest mod of all: it is just a folder of text files, and Minecraft reads it for you.
For this whole series: a computer, Minecraft Java Edition and this website. Datapacks need no mod loader, no install and no admin rights.

Go further with mods: datapacks are the no-install way. When you want new blocks, items, tools and mobs of your own, the Fabric mod series takes the next step (it needs a free Java install and a grown-up).
