Welcome! This is going to be quite the journey, and like all journeys, this one starts with a single step. Our first step is to take inventory of bit of content on CSS-Tricks. Starting with this means that we won't be forgetting or neglecting any particular area of the site as we start thinking about the new design, because we've just recently explored every little nook and cranny of the site. This will also give us a quick content reference if we need it and also act as kind of a checklist later on in making sure we've addressed everything, design-wise.
Taking inventory is also a great first step for content strategy work, which we'll get to very early on in this design process. It will also help us attach goals to different things on the site.
Perhaps not the most exciting start, but a vital step.
