 I have no idea why Unity choose to not make its WebGL exporter default
 to filling the window like pretty much all other WebGL apps on the net
-but in any case here is a minimal template
+but in any case here is a template
 
 Example: https://greggman.github.io/better-unity-webgl-template/
 
+## Instructions
+
 The short version is you just need the `Assets/WebGLTemplates/BetterTemplate` folder
 in your project. Then pick `Edit->Project Settings->Player`, in the WebGL tab
 under *Resolution and Presentation* pick "BetterTemplate".
