To install a theme on your Magento, Start by creating your theme folder in the app/design/frontend directory or in case you have a compressed theme file, unzip it here and your final path will be : app/design/frontend/Vendor/ThemName

After then run the below commands

php bin/magento setup:upgrade;
php bin/magento s:d:c;
php bin/magento s:s:d;
php bin/magento c:f

if you are creating your custom theme then you can follow this link :
