cd /absolute/path/to/your/magento/folder
php bin/magento setup:static-content:deploy

If you are using Windows, then make sure you added PHP executable file to your Environment Path, after that open up your Windows Command Prompt (cmd) and:

cd /absolute/path/to/your/magento/folder
php bin/magento setup:static-content:deploy
