Snapchat is confusing, so here's how the company is teaching older investors how to use it (SNAP)

Snap's main product, Snapchat, has a reputation for being difficult to use, especially if you're not part of its target market of teens and young millennials. 

But since it's asking investors who are typically older to invest in its IPO, Snap included a handy 10-slide guide to navigating and using the app, which has 158 million daily users, according to a financial filing published on Thursday. 

Here's how to use Snapchat, the disappearing messages app, according to Snap:

Here are the five main screens that comprise Snapchat.

Let's take a look at the first screen you see, the Camera screen.

Making a Snap is simple. Users either tap the Camera button to take a photo, or hold the Camera button to record a video up to ten seconds long. Immediately after a Snap has been created on the Camera screen, the Preview screen displays the photo or video Snap for the user to review and edit using our Creative Tools.

From the camera screen, you can turn on "Lenses," that transform your face into a dog, or a taco, or other fun cartoons.

The Camera serves as the interface for our Creative Tools. Most of these tools are available on the Preview screen after a user takes a Snap, but Lenses are used on the Camera screen before taking a Snap.

When you tap on the screen, the Camera focuses and detects objects in the scene. For example, if a user taps on his or her face, we immediately show Lenses at the bottom of the screen, adjacent to the Camera button. Lenses are interactive animations that are overlaid on a person’s face or the world around them. A user can easily create a Snap while using a Lens.
