40: Update running an example documentation r=kvark a=Napokue
- Removed link to gfx getting started
- Created our own getting started (with examples)
- Updated syntax
Motivation: I always forget how to run the examples, gfx getting started is not the same as the wgpu-rs one. So I found the correct usage of the syntax to run examples. I am noticing in the Gitter channel that many people are struggling with running the examples, maybe this will clear it up a little.
This is the beginning, I will continue to expand the documentation in the future.
