I'm here staring at the front page of the wiki, feeling a desire to correct some errors and share my unhinged thoughts unique wisdom with the world.
Does this sound familiar? Are you thinking this right now?
Great! Let's get started on our journey to chaos.
First off, you should pay attention to the note that the wiki is split into two sections. People go under People, everything else goes under Lore. This will be important later.

Before you can do any editing you must log in. That's right, this is a members only club.
Pull on your stylish windbreaker (fashion) and click the Hatman user icon in the top right.
You've undoubtedly seen a log in screen before and know what to do here.

What's this? Back at the start page? Vexing!
Before you give in to the intrusive thoughts, notice there are now 5 icons on the right, instead of two.
You're now logged in and can edit! Oh, the world is our oyster. We can edit the… or the… well, what about…
Our hivemind is overwhelmed with possibilities. Let's start somewhere modest and topical: The Holiday Album!
That's lore, not a person. We will also take for granted that it does not exist. When you're editing on your own, you'll need to check to see if a topic is already covered and think carefully about what to name it.
So, right then, we want to make a new page. I should just click the new page button right over… huh.
You're not mistaken, dear reader, you cannot find that button. The wiki cleverly and frustratingly only lets you make a new page if you cannot find one via searching.
You shall meet the next boss of our quest by searching for the holiday album. We know this should be under lore (remember when I told you to READ THE NOTE in step 1?) so we'll search for “holiday_album” and preface it with “lore:”.
In Wiki terms, that means we want to find “holiday_album” in the “lore” section. The alternative is chaos, but not the richly flavored and frosted kind we want.

No results found? Oh, how could it be, the very outcome we expected!
Read the page and click the red text to create the page.

Ah, a blank canvas on which to spray our mental diarrhea. How shall we begin?

A title! Like Shakespeare we shall whet the readers appetite with a few words summarizing our masterpiece.
Click on the H button to create a Level 1 Headline.

What a brilliant title! Oh, we can imagine the clamoring of eager reader's murmurs and gnashing of teeth already!
Follow that up with a few informative statements. Soon the unwashed masses will know the truth! Lead them from the darkness, oh light bringer!

Perfect… for any other soul. You, my dear, are exemplary and will go a few steps further.
You'll select some text to link to other articles. Now you'll click on the button with the links of chain. Let's not dwell on innuendo, we're being prompted to select the target of our link.

A few deft keystrokes and the box found our target - the Hive Mind.
Click on the item to select it.

A few more links to make things spicy and.. no! How could this be!
A LIE on our otherwise perfect page. This couldn't be an accident, oh no, we're much too good for that.
This is a deliberate imperfection. To call it out as such, select the text and click on the button with the crossed out S.
Perfect.

Before we reveal the page to the world, I urge you to do one last check.
Click the preview button to see how this will look in the eyes of others.

Sacre bleu! This little section reveals the Matrix beyond the Wiki markup source code.
Oh the horror! Quickly, click the Save button lest we dwell forever in the perspective of a non-editor!

And so it is done, our profound work is committed in perpetuity for posterity.
People will find it, perchance. Yes, perchance if they search. Perchance we should link to it from another page.
Perchance.

The Lore page acts as a directory to find the major articles describing lore.
We should give our article its own star on this Hollywood walk of fame.
Navigate to that page and we'll edit it, much as we just edited our own page.

Placing our cursor on a fresh line below the the last entry in Activities, we'll then click the link button again.

Selecting our page and clicking save…

Et voilà! We're done! BEHOLD!
