The Nosto Magento 2 extension requires at least PHP version 7.0.0.
Installing the extension
Currently the only way of installing the extension is via Composer. If you don't have composer installed yet you can get it by following these instructions. It's recommended to install composer globally. You will also need public key and private key from Magento Marketplace or Magento Connect in order to install packages to Magento 2 via Composer. Please follow these instructions to get public key and private key http://devdocs.magento.com/guides/v2.2/install-gde/prereq/connect-auth.html. Once you have composer installed you can install Nosto extension (nosto/module-nostotagging).
You might need to change file permissions or ownership of the generated files after the installation.
After running the commands above you can login to the store admin. You will find Nosto -link under Marketing section.
Magento's repo does not contain the latest release
In case you are pulling the dependencies from Magento's repository repo.magento.com and you encounter an error where the latest release is not present, you can exclude Nosto packages and instead pull them from the default repository https://repo.packagist.org/.
We strongly recommend that you set the mode for Nosto indexer(s) to be "Update by schedule". This is important especially with large product catalogs and / or when using multiple store views. Read more about indexer performance and optimization here
