+All the strings can be extracted from the application using a command:

+
+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.
