How do you use Custom Fonts?

I’ve created a custom font, set up the character rects for numbers 0 - 9 with the correct UVs. I can’t get the thing to render either using OnGUI.Label, 3DText or using GUIText. The documentation on this is weak, practically non-existent and I can’t find any decent tutorials. The docs don’t say what shader to use but I assume GUI/Text Shader? Am I missing something glaringly obvious here?

Thanks in advance!

This tutorial involves the importation and use of a custom font, it should be of aid to you. The tutor uses it in his main menu, as a GUI text.
