Not sure what you're expecting in the way of instructions. Here's what Adrian and I did. Draw SVGs in Illustrator. Upload them to icomoon.io. Have them build a font file ... actually, they'll make a whole ZIP for you with .svg, "debug" .svg, .ttf, .woff, .eot, an HTML preview, etc. Extract ZIP (and, actually, its contents were already committed to the oerpub.uidesigns.editor repository). Move files to my GitHub folder (and cross fingers that scripts/gh-book/ was a good enough location). Rename files. Commit.
