+# Style protobuf
+
+We're encoding the styling information as a protocol buffer, according to
+proto/style.proto. The reason for doing so is that we don't have to ship with a
+JSON/yaml parser. To test the conversion script, run
+
+```
+bin/convert-style.js | protoc --decode=style proto/style.proto
+```
