We'll come back to these events later.
Now go into the Audio tab, and find the "Actor-Mixer Hierarchy" section.
Under the section should be the Work Unit you imported previously. It'll contain the containers that you import your audio (.wav) files into.
Due to how Wwise handles imports, there are 2 settings that need to be applied for the audio to both work and sound good.
We're editing these Containers:

Output Bus
The first field that needs to be changed is the Output Bus

Click on the 3 dots next to it, and navigate to:
Master-Mixer Hierarchy > Default Work Unit > Master Audio Bus > Main > SFX > Environment

Select Alarms and click OK
Global Obstruction
Next, go into the RTPC tab in the Container Property Editor

This tab will be responsible how much the audio will lower when it comes to walls, doors, and floors being in the way.
Due to how much this is up to you, this is a separate page entirely that can be opened here.
Audio Importing
Importing audio is easy. From file explorer, select the audio you want to use, and drag it onto the respective Container.
A window will open on import settings, for this you want to import it as a Sound SFX. Everything else can be left on its default setting.

If you want a preview of what to expect, Wwise has controls to play, pause, and stop the currently selected container/audio.

By default, the Random Containers3 provided will loop 15 times. If you don't want this, change this field:

Once you're happy with your work, go back to the Events tab.
Events, again
Open the events that were created previously, a window like this should be open:

On the bottom left, there's an option to "Add >>". Click on it, and click "Browse Object..."
Then search for the Container3 that you want to play, whenever this event is triggered.
Once you find it, select and press OK.
Go ahead and do this to the other potential events, unless you have another container to play for it.
Paking
Press "Ctrl S" to save, and open the Unreal Engine Project you downloaded in First Time Setup1
Proceed to "Paking Your Mod" on the left hand side of the page
