+🎒 1. datapacks/ — Minecraft’s built-in modding system
+
+Datapacks are Minecraft's official way to add game logic without mods.
+They let you create custom:
+
+Recipes
+
+Loot tables
+
+Structures
+
+Commands/functions
+
+Dimensions
+
+Advancements
+
+Worldgen features
+
+Mobs (via loot, behavior triggers, etc.)
+
+They live inside:
+
+world/datapacks/
+
+
+or in a custom world folder of your choice.
+
+Example structure:
+
+world/
+  datapacks/
+    my_custom_pack/
+      pack.mcmeta
+      data/
+        minecraft/
+        mypack/
+
+
+How they work:
+
+When the server starts, Minecraft automatically loads all datapacks in that folder.
+
+You can reload them live with:
+
+
+/reload
+
+Why track them in Git?
+
+Because datapacks are basically tiny “mods” made out of text files.
+Git lets you:
+
+Version your changes
+
+Roll back bad ideas
+
+Experiment
+
+Collaborate
+
+Deploy from laptop → server instantly
+
+Keep a history of your custom world logic
+
+For a Vanilla 1.1 server, datapacks didn’t exist yet — BUT if you're doing a modern-style organization or planning forward, Git still handles it well.
+
+
+
+🌍 2. dev-world/ — A safe test world
+
+This is NOT a built-in Minecraft feature — it’s a practice/testing world folder that YOU create.
+
+Purpose:
+👉 To test datapacks, commands, NBT edits, worldgen changes, and dangerous experiments without ruining the real world.
+
+What it looks like:
+
+dev-world/
+  level.dat
+  region/
+  playerdata/
+
+
+Basically the same as your real world/, but:
+
+You can reset it anytime
+
+You can duplicate it
+
+You can try insane commands
+
+You can prototype datapack functionality
+
+You can test structures/commands with no consequences
+
+How to use it:
+
+You temporarily point your server to use dev-world instead of world.
+
+In server.properties:
+level-name=dev-world
+
+
+
+
+Start the server → it loads the dev world.
+When you’re done testing, switch back:
+
+level-name=world
+
