+## Simple method to generate a font
+
+If you want to generate a basic font containing only numbers and letters, you can use the above settings but instead of specifying a range, simply list the characters you need in the Symbols field and leave the range blank. This is the approach used for the PineTimeStyle watchface.
+This works well for fonts which will only be used to display numbers, but will fail if you try to add a colon or other punctuation.
