Hello @com4digital,

All the strings in the theme are already made translation ready so you can change those string in your desired language.

To translate the string in your desired language you can use the plugin like loco translate.

After translating all the stings make sure to set the site language in your desired language by going to Admin Panel > Settings > General > Site Language.
