Installing Magento CE 2.0 on Ubuntu on Virtualbox

[Brian1111]

Can anyone explain how to install Magento CE 2.0, on Ubuntu 14.04, on Virtualbox, on localhost?  I have already spent four days on this; still I cannot figure out how to install it.  I was able to successfully install nginx and set up mysql.  Thanks.

Did you download Magneto2 or are you trying to install it from GIT?

I downloaded Magento 2.0 CE to Ubuntu Downloads folder and extracted it.  I don't know how to install it from GIT.
