The extension works with Magento CE versions from 2.0 upwards. Please note that Magento versions 2.0, 2.1 and 2.2 have reached or will reach their end of support soon. Therefore no new extensions can be published in the marketplace for those versions. If you are using one of those versions, please send us an email to email@example.com
To install the extension, simply go to Magento Marketplace and install the app. Make sure that your Magento instance has multiple store locales configured.
