+Skin fitting the Mediawiki 'vector' theme, for use with the [Game Making Tools wiki](https://www.gamemaking.tools/wiki/).
+
+## Installation
+
+- Requires the Mediawiki extension 'Theme': https://www.mediawiki.org/wiki/Extension:Theme <br>
+See instructions behind that link (you just put stuff in a folder and add a line to LocalSettings.php).
+
+- Place this stylesheet within your wiki's `extensions/Theme/vector` directory (Vector is the skin it modifies).
+- Within `extensions/Theme` there's a file called `extension.json`. You need to find the `ResourceModules` bit and add the theme there. For example mine looks like this:
+```
+"ResourceModules": {
+	"themeloader.skins.vector.gmt": {
+		"styles": {
+			"vector/gmt.css": {
+				"media": "screen"
+			}
+		}
+	}
+},
+```
+- NB: I only have one theme set-up though! Each theme you want to use needs it's own 'module'.
+
+## To-Do
+
+- Clean up some of the hacky feeling bits (mostly to do with the logo).
+- Mobile version.
+- ? Maybe shift styling of infoboxes to CSS instead of in the template.
