Translations
PrestaShop provides you with full translation tool for your shop. This helps
you add and edit the current translations. This way, you are the master of
your shop, and can handle your translated strings without having to wait
for translators to publish their corrections.
Even if you do not want to correct the translators' work, you might want
to change the wording they chose to use (less formal, less wordy, etc.),
and customize the various available text, thus tailoring your website to
your audience (for instance, a hip-hop clothing shop might be better off
using expressions different from that of a luxury watches shop).
"Translation exchange" section
The "Translation" sub-tab provides a few tools for your translation needs.
