 #### Preset Properties
 
+##### `countryCodes`
+
+An array of two-letter, lowercase [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) country codes. The preset will only be searchable when the user is editing over the specified countries. The locale and language of iD are not factors, just the position of the map.
+
+By default, presets are available everywhere.
+
 ##### `fields`/`moreFields`
 
 Both these properties are arrays of field paths (e.g. `description` or `generator/type`).
