Install the Module

Run everything from your Magento root directory, as the web-server user or with the correct file permissions.

From a downloaded archive

After buying the extension from the Webkul Store, unzip it and copy the files into app/code/Webkul/. Copy every folder from the package's Webkul directory, not only ZohoSso:

<magento-root>/
└── app/
    └── code/
        └── Webkul/
            └── ZohoSso/
                ├── Block/
                ├── Controller/
                ├── etc/
                ├── Helper/
                ├── i18n/
                ├── Logger/
                ├── Model/
                ├── view/
                ├── composer.json
                └── registration.php

Create the Webkul and ZohoSso folders yourself if they do not exist.

With Composer

If your Webkul Composer repository is configured:

composer require webkul/zohosso

Next: Enable & Compile.
