If you want to edit, add or remove any icon in our CartoDB font, you should follow these steps:
- Check you have [Sketch](http://bohemiancoding.com/sketch/) last version.
- Open [font.sketch](http://github.com/CartoDB/CartoAssets/blob/master/icon-font/font.sketch) file and make your changes.
### Rules for the icons:
- Size should have at max 500px of width/height.
- Place the icon accordingly with the grid.
- Icons should be completely black.
- Group the icon if it has several parts.
- Make icons exportable to SVG.
- Name your icon (layer/group) according to the pattern `icon-font_xx_Name`, where xx is a unique integer (increase it for each new icon).
### When you're done with changes
- Select all the icons, and export them to `app/assets/fonts/icon-font/svgs` folder (option should be visible in the bottom corner in your Sketch app):

- Take into account that ```svgs``` folder is ignored.
- Open your terminal app and go to the CartoDB root folder.
- Install your node dependencies: `npm install`
- Now we will generate the new icon fonts + stylesheet. Just run: `./node_modules/.bin/gulp`
- Check that your `icon-font.css.scss` and the `cartoIcon` fonts have been edited:
