To install the extension

1. Log in to the FTP, and then go to Magento 2 root folder (generally present under the public_html folder).
2. Create a new folder named code under the app folder; under code folder, create a folder named Ced.
3. Now you have to extract two files:
   • Firstly, extract the vendor/cedcommerce/seller-center-sdk-php in the vendor/cedcommerce/*
   • Secondly, extract the Ced/Zalora, Ced/Integrator in the app/code/Ced/*
4. After extracting the above package, we move on to adding the SDK mapping.

   • Perform the following 2 actions in autoload-ps4 node:
     1. “RocketLabs\\SellerCenterSdk\\Core\\”: “vendor/cedcommerce/seller-center-sdk-php/src/RocketLabs/SellerCenterSdk/Core/”,
     2. “RocketLabs\\SellerCenterSdk\\Endpoint\\”: “vendor/cedcommerce/seller-center-sdk-php/src/RocketLabs/SellerCenterSdk/Endpoint/”
