-# Hello World
+## Introduction
 
-# Hello World
+As to tradition, we're going to start learning how to mod Minetest with "Hello world!" However, we're going to do it a bit differently. We're going to start by making a Hello World Pickaxe. Are you ready?
+
+## Where?
+
+To mod in Minetest, we have to put our files in the right spot.
+
+ * Windows: `minetest-install-path/mods`
+ * OS X: `minetest.app/Contents/Resources/bin/mods`
+ * GNU/Linux: `~/.minetest/mods`
+
+The Windows' location depends on where you installed it. Whatever you're using, just ask if you need help.
+
+When you first start, the `mods` folder won't exist. You'll have to make it. Just make a new folder and name it `mods`.
+
+## Setting Up
+
+With the `mods` folder ready, we can start with our special pickaxe mod. We have to make our project have its own folder and get the parts for it all together.
+
+1. Make a new folder inside of `mods`. Name it `helloworld`.
+2. Inside of the new `helloworld` folder, we make a new file named `init.lua`
+3. Make a new folder next to your file. Name it `textures`.
+4. Save this `helloworld_hellopick.png` image into the `textures` folder.
+
+This is the basic setup we need for this mod we're making. We gave it its own folder, `helloworld`, and then we setup the pieces it will use. `init.lua` is the file we will put our code in. The `textures` folder will hold our image for our pickaxe, that image being `helloworld_hellopick.png`.
+
+## First Code
+
+Open up `init.lua` in your editor.
 
 ```Lua
-minetest.register_tool("tutorial:hellopick", {
+minetest.register_tool("helloworld:pick_hello", {
-	inventory_image = "tutorial_tool_hellopick.png",
+   inventory_image = "helloworld_hellopick.png",
 })
 ```
 
+Notice that there are parenthesis (`( )`) and braces (`{ }`). It might help to see it this way instead.
+
+```Lua
+minetest.register_tool("helloworld:pick_hello",
+   {
+      inventory_image = "helloworld_hellopick.png",
+   }
+)
+```
+
+When you've copied it down just like that, save the file.
+
+## Trying the Pick
+
+Let's check out our Hello Pickaxe now! Start up Minetest.
+
 Made like Stone Pickaxe, plus Hello World output.
 ```Lua
 minetest.register_tool("tutorial:hellopick", {
