To install the Origin Theme you must first have a working WordPress(.org) installation. For information on installing WordPress, please see Installing WordPress, from the WordPress Codex. Once WordPress has been setup in your hosting environment, you can install your theme one of two ways:
FTP upload: download and un-zip your theme folder, and using the FTP program of your choice upload the theme folder to the ‘../wp-content/themes/’ folder on your server.
WordPress dashboard: download your theme and sign into your WordPress dashboard (e.g., yourdomain.com/wp-admin). Navigate to Appearance > Themes > Add New > Upload, and select your zipped theme folder, click “Install Now”. Once the theme is uploaded you will need to activate it, either with the provided link or under Appearance > Themes.
Note: If you use Safari as your primary browser you may find that your theme folder is not zipped after downloading it. You will need to re-compress your theme folder before initiating the second installation process.
