+The whole application is prepared for localization. All the text can be exported from the user interface and translated into several languages. The numbers, dates, and time values are also formatted with respect to the selected language. The [react-intl](https://github.com/yahoo/react-intl) and [Moment.js](http://momentjs.com/) libraries are used to achieve this.
+
+All the strings can be extracted from the application using a command:
+```
+$ npm run exportStrings
+```
+This will create *JSON* files with the exported strings for the *'en'* and *'cs'* locale. If you want to export strings for more languages, you must edit the `/manageTranslations.js` script. The exported strings are placed in the `/src/locales` directory.
