Hello! Thanks for buying this template!

It's really easy to customize:
1. Open “Navigation” comps and copy elements to your composition
2. If you want to customize element, open composition with the element and click to “Effect Controls” to customize it.
   -To change the color, change the "Color" effect
   -To enable or disable the glow effect, tick the checkbox
   -To change glow radius change the values of the parameters "Glow Radius" 
3. Render your composition.

Thats all. 
Hope you like it,
Best regards
