So the first thing you're going to do is set your bokeh size, as how far the deltas are from each other will change based on this size. When I say, "light circles", I'm referring to this effect:

Changing bokeh size will change how big these circles get, basically making the image appear more or less blurry in the distance. It also in effect changes how wide or narrow your focal depth is. I usually go for somewhere between .2-.4, but you can play around with it to find the setting you like. Just be aware that if you change it you will have to realign the focus deltas so try to do this first in your process so you don't have to realign over and over.

Next, on to focus deltas. WTF am I even talking about? Well, the way this generator works is it captures frames between multiple different angles and combines them to generate the field depth. When you first start the DoF session, you are going to see two versions of your image overlapped and offset from each other, each one from the opposite "end" of the angles the generator will be using, like this:

Aligning the focus deltas to match up with each other is how you pick where your image is focused. In most cases you will be using a character's eyes as your focal point, but you can make it anywhere, whatever spot you align the focus deltas on is what will be in focus. Here's the generated image with the focus on the character:

And here with the focus on the candle holder in the background:

As you can see, wherever you align the focal deltas is where the camera will be focused.

Now let's take a look at the magnifier tool:

This is basically just a zoom-in window so you can align the focus deltas more precisely. You can change its size and position to get it to where you're trying to adjust the focus. Move and resize it however you need so the point you want to focus on is in the window. Then move the focus delta values around until both versions of your focal point are aligned with each other. Now your image will focus on what you've chosen as the focal point.

Now, one thing with focus deltas is that if your focal "point" is spread across more than a single focal depth, you may need to "split the difference". For instance, due to the 3/4ths angle, the eyes here are at slightly different depths, so if you look at the edge of the face in the magnifier window you will see some slight pixel overlapping instead of it being lined up perfectly. Usually in the generated image this isn't noticeable, but you can exaggerate it using large bokeh size and focusing on a single point instead of splitting the difference if you want to get a super narrow DoF, where, for instance, only one side of the face is fully in focus.

So you've aligned your deltas. Now what does the rest of this stuff do? The rest of the settings affect the "light circles" created by the bokeh effect. This generator creates them by rendering tiny points of light in a circular formation. The first two settings affect how many points are in each circle. Let's take a look at how they compare when using lower quality settings vs higher:

Low quality:

vs high quality:

As you can see, in the lower quality image the "points" are clearly visible. However, higher quality settings take significantly longer to process as they utilize many more individual frames than lower quality. You can mess with these to find a balance of speed vs. quality that you prefer. Render order just changes the order the points are generated in, but I haven't found changing this to make too much of a difference.

Last two settings affect the brightness/contrast of the "light circles". Here are some examples of the same lights with different settings:

Not a huge difference, but I find that a sharper, more pronounced bokeh will give the image more of a "cinematic" feel since it's such a distinct effect caused by the way real cameras work.

Finally, let's go back to the setting I skipped over- the "Frames per frame" setting. If you are freezing the image with the camera tools beforehand, you will probably not need to mess with this setting. If you are taking screenshots without freezing the game, however, you may need to increase this setting slightly, otherwise the generator may not compensate for, say, your character shifting slightly during their idle animation, and the foreground will come out just as blurry as the background.
