+FontFace
+========

 Watch Face for Pebble, like the built-in "Simplicity",
 but with a better font.

 each with the same functionality but different appearance.
 
 I like fonts, okay.

+Building
+--------
+
+The `pebble` SDK tool makes a lot of assumptions
+about how your directory is set up.
+In order to build multiple projects from the same source tree,
+I created a `build.sh` script,
+which shuffles things into the right places,
+runs `pebble build`,
+then renames the generated files.
+
+You can also use `build.sh`
+to experiment with new fonts.
+Simply drop the `-Regular` and `-Bold` variants
+of your font into `resources/fonts`,
+and run `build.sh $FONTNAME`.
