First, you must create a new folder on your domain or a new subdomain.
To upload the files on your domain, you have 2 options:
1. Login into your Cpanel/Hosting admin area and go to "File manager" section.
Navigate to the new created folder/subdomain and upload the zip package.
Then use the "Extract" option. Continue with the next step of the installation.
2. Unzip the package on your local computer, then connect to your server using any FTP client(Filezilla, Winscp).
Upload all unzipped files in the new folder. Continue with the next step of the installation.
