Unable to install extension in magento 2.0

[mscart]

Hi,

I am new to Magento, I installed magento using Digital Ocean image. Everything seems to be working fine except extension. Any help will be very helpful.

For now (while Magento 2 Marketplace is not ready yet) you should install Magento 2 extensions through the Composer.
