-**What you'll need**
+##### What you'll need
 * The [Tiled](http://www.mapeditor.org/download.html) map editor
 * A text editor like [Sublime Text](https://www.sublimetext.com/), [Atom](https://atom.io/) or [VS Code](https://code.visualstudio.com/). Notepad could work too but let's not make it harder for ourselves?
 
-**Prep**
+##### Prep
 * Create a new folder in `server/config/maps`. The folder should't contain spaces and should ideally be your map name. For instance: `plainsOfRuin`.
 * Download the map blueprint from [here]().
 * Extract the zipped archive into your new map folder. You should now have `server/config/maps/{yourMap}/map.json`.
 
-**The Map File**
+##### The Map File
 
 Open the `map.json` file in Tiled.
