Let's start from the very beginning... I know that many people already know how to start with a Raspberry Pi, but for beginners this could be somehow difficult.
In this post I will try to explain the various steps to follow in order to have a Raspberry Pi that is usable without problems.
All my future posts will be based on these steps, unless stated differently. Also I use Windows on my computer to perform some of the steps, so if You need to start from a different system You can go here to find more info about starting from Mac OS or Linux.
