Problem with tutorial, can't open game

[keen harness]

Is there someone who can help me get started with Fabric modding? I am following this tutorial, but it seems that it is already outdated. I've done everything shown in the video

If you're developing for 1.21, it should be fine. If you're having a specific problem, feel free to ask. We need details to help.

Sure thing! Sorry for not clarifying.
I chose to develop for 1.21.8. I have just made a single item, however, each time something is wrong:

• Either, the item shows up in-game, but the texture doesn't work
• The client can't start at all
• The item is missing

Yeah, there's been major changes since 1.21. Minecraft is like that. https://docs.fabricmc.net/develop/items/first-item is up to date for 1.21.8

There has been a change to the resources.
You now need to add a file at:
assets/MODID/items/itemid.json

Inside that file, you can specify the model like this:
{
"model": {
"type": "minecraft:model",
"model": "MODID:item/itemid"
}
}

So, to add a custom item, you will need the following files:
assets/MODID/items/itemid.json
assets/MODID/models/item/itemid.json
assets/MODID/textures/item/itemid.png

i've fixed the docs page to highlight that you need all 3 for the item to appear correctly
