Icomoon Font Icons
All icons downloaded through Icomoon will be installed as font icons. The benefit to Icomoon is that you can select from a huge library of icons, ranging in style and icon type, and quickly download a preconstructed .zip file with everything you need to get going. Icomoon is also free and doesn’t require any account registration.
Head over to Icomoon to get started. You should see something similar to the following:

If you’ve chosen to import additional icons from one of the Icomoon icon libraries what you see may look different then what’s above. The important thing is that you’re seeing icons in a grid, that you are able to select from.
Go through and select any and all icons you want to be included in your icon set.

Once you’ve selected all the icons you want to include in this icon set click on Generate Font in the bottom right of your screen.

Next thing you’ll want to do is customize the preferences of the icon font. This is where you can set the Font Name and the prefix of your custom icon set.

Once you’ve updated the preferences to your liking you can close the preferences window and click Download, again in the bottom right of your screen.

That’s it! Take note of where the .zip downloaded to as you will need it again to upload back into WPIcons Pro.
You can now proceed with Installing the New Icon Set.
