Modding Tutorial by kahrl - Minetest

Here's a start, but feel free to go in a completely different direction.
Note, I've often only thought about what concept the tutorial will be about, but still need to come up with a fun way to demonstrate it.

Mandatory
Every modder should read these.

1. Getting started: This will give some basic information, show how a mod directory is set up, and define a new node type.
2. Terminology: Gives an overview of the modding terminology, and some initial insights into the game engine.

Beginner
The beginner tutorials will explain one simple concept at a time, and don't go into much detail.

1. Nodes: This will continue the "Getting started" tutorial and explore some of the simpler settings for nodes.
2. Inventory: Explains itemstrings, and how to customize the give_initial_stuff mod.
3. Crafting: This will show how to define new crafting recipes.
4. Tools: This will show how to define new tools and their digging properties.
5. Items: This tutorial demonstrates how to define a craftitem and explains the callbacks.
6. Commands: This shows how to define a simple new server command. Not sure what this could be about. Maybe a /lightning command that damages all players? :O
7. ...

Intermediate
These tutorials could explain more difficult concepts or expand on the info in the beginner tutorials.

1. Engine details: Not directly a tutorial, but explains some of the engine details that don't fit into the "beginner" section, like active blocks and so on.
2. ABMs: Shows a very simple ABM. Maybe one that converts cobble next to water to mossy cobble?
3. Entities: This tutorial shows how Lua entities work. Again, what could it be about?
4. Buckets: This will explain (in detail) how the existing bucket example works.
5. Mapgen: How to run a callback each time a new mapblock has been generated, and do some fun stuff with it.
6. Node parameters: Explains what nodes' param1 and param2 do. Maybe multiple parts, one for param1 = light value, one for param1 = facedir, another one for param2 things?
7. Node metadata: Could show how to make a mob that vandalized all signs it finds. :D
8. ...

Advanced
These will explain, um, advanced concepts or show how to combine several simpler steps to make a great mod (for science!)
TBD.

I'm quite sure I have forgotten something! Also, if anyone has an idea to get the tutorials into a logical order, that would be neat.
