[ALOY-255] Assess/Improve Alloy Documentation

Let's assess the current state of Alloy's documentation: * Do we have good coverage from the docs provided by the docs team? * If not, where do we need improvement? * Should the quick start be updated with more samples? Perhaps separate tabs sections for high level Alloy concepts like view/controller creation, using models, etc... * Do we need to consider wiki/training docs? Any work resulting from this ticket will be put into a ticket of its own.
