Is this possible?
If that's your question, the answer is yes, although that is clear in the Q&A you link to -- which goes a little bit further in terms of asking how is this possible, and has an accepted answer already. If that answer does not work for you, feel free to reference it in a more specific question, detailing what you actually tried to do and what specific problems you had.
If you are not familiar with the general format of Stack Exchange, of which this Raspberry Pi site is a part, you might want to familiarize yourself via the tour (also accessible via "help" in the top bar). It is NOT a forum, meaning, the paradigm is NOT to introduce a topic on which you are seeking some input, have someone reply to you, then you respond to them, and a dialogue ensues. Instead, the goal here is to present questions (again specific questions) -- in as polished and well thought out manner as you can -- and then receive definitive, conclusive, specific answers. Not open ended dialogue.
Which is not to say there is anything wrong with forums and open ended dialogue, but there is already a raspberry pi forum, and this is not it. Part of what's at issue with your particular question is that, as you yourself point out, it has already been answered, and an explicit goal of the Stack Exchange format is to avoid repeated discussion of the same topics over and over again.
So, do your best with the information already available, and if you find specific points unclear, then feel free to add to the available information by asking about them, rather than obliquely asking for a re-hash ;)
