 ## Features
 
 - Works with both WebGL and WebGL2
-  > The former is mostly required for supporting iPhones.

 ## Usage (1st option)
 
-- To start using cutting-edge 2D graphics, first you have get a renderer instance. This is possible by calling the [compile function](globals.html#compile).
-  - For this, some [DrawableDescriptors](interfaces/drawabledescriptor.html) has to be provided.
-  - Optionally, default compile settings can overridden using [StartupSettings](interfaces/startupsettings.html).
-- After acquiring a renderer, the drawing of objects can be started through the [Renderer](interfaces/renderer.html) interface.

 ## Useful to know
 
 ### Math
 
-The `vec2`, `vec3`, and `vec4` types seen in the documentation come from the [glMatrix](http://glmatrix.net/) library and are equivalent to regular JS Arrays or Float32Arrays. So, feel free to give `[x, y]` as an input for functions requiring `vec2`.

 ### Coordinates
 
-Anywhere, where positions need to be specified, the `y` values grow upwards. That means, when setting the view area, the origin is at the bottom left corner of the display.
+Wherever positions need to be specified, the `y` axis grows upwards. This means that when you set the view area, the origin is at the bottom-left corner of the display.
 
 ### Tile-based rendering
 
-For optimising the evaluation of the distance field, the display is divided up into a grid of tiles. The shaders for each tile are compiled to support a fix maximum number of objects on it. When using the built-in drawables it is possible that after a certain number of on-screen objects new ones won't be visible.
