The plugin includes .po/.pot translation files. I recommend using Loco translator and settings the text domain and filename-prefix to “fsww”.

1. Go to the page Loco Translate > Plugins.
2. Click on FS WooCommerce Wallet.
3. Click on Advanced.
4. Set the “File prefix” as “fsww”.
5. Set the “Text domain” as “fsww”.
6. Save.
7. Click on “Overview”.
8. Click on “New language”.
9. Select your language.
10. Click on “Start Translating”.
11. Translate the text.
12. ​​​Save.
