Step-by-step instructions on how to embed a resource pack in a Minecraft: Java Edition world

Universal

Locate your world that you want to embed the resource pack. All worlds are stored in .minecraft/saves
Now, Compress your resource pack to a ZIP file ensuring the pack.mcmeta is located at the root of the ZIP file.
Rename the ZIP file to resources.zip and place it inside your world folder. The location should look something like this. .minecraft/saves/New World/resources.zip
Done! The resource pack will now be loaded when you enter the world and unloaded when you exit.
