There are a couple of typos, but more importantly, I do not know if we should use an image of the D-Wave chip (especially if we do not have copyrights on it). I would rather remove it.

We took the image from wikimedia commons. I think we should have, if not this one, at least a figure to motivate and catch people's attention with shiny alien-like hardware.

@bernalde we found this image on Wikimedia, so it should be copyright free. But I feel that it is not contributing to the documentation too much. I can remove if you all agree

I had to comment these lines because the different dispatches for ToQUBO.toqubo_constraint weren't showing up on the docs. Does anyone know how to solve this?

https://github.com/psrenergy/ToQUBO.jl/blob/e56193c93d10ad18d8b191dc157f577d9d8de63f/src/compiler/interface.jl#L57-L61

[bernalde]

Is this ready to merge?

[pedroripper]

I'll just review if we have checked everything from #63
