Page: Getting started

[iver56]

Add a page that explains how to get started

• Some basic techniques (how to draw a filled rectangle, a line, an arc, how to color them, how to draw multiple things, how to clear a frame etc.)
• Examples of the techniques mentioned
• A few words of advice on how to avoid getting in an "infinite loop" state (be careful when editing a for loop)

#10 is relevant to last item... Might be useful to point to https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Drawing_shapes for example...

Might I add a suggestion of adding a "comment/about" section for each demo where the author can explain the technique/code for the demo? (in addition to the comments ofc)
