 5. if you're submitting changes to OpenHistoricalMap please begin by creating an issue that describes them at our [issues repository](https://github.com/OpenHistoricalMap/issues/), which is different from [where you'd submit your pull request](https://github.com/OpenHistoricalMap/map-styles).
 6. when you're satisfied with your local changes, repopulate the `dist` directory by running `npm run build`; the build step replaces references to `localhost` with the production values of the OpenHistoricalMap servers for `glyph` and `sprite` serving; this is required prior to deploying to OHM's staging and production servers. If you're hosting your own fonts or icons you'll need to edit these for your custom use.
