I did regret having no reference which I could have referred back to earlier. As a result, I've put together this gist, so that it guides me through the same process I follow when I completely reinstall the system every so often.
Borrowed a couple of steps and pieces of advice from https://gist.github.com/millermedeiros/6615994.
First off, make sure everything's is up to date. To do so, head over to "System Preferences" -> "Software Update".
