Here are your instructions for installing the WP-Dimension theme.
Using this theme requires a self-hosted--or institutionally hosted (lucky you)-- Wordpress site (the kind that you download from wordpress.org. You cannot use this theme on the free "wordpress.com" site unless you have a business plan. Maybe check out Reclaim Hosting if you need to set up your own hosting space. They are awesome.
You can download a .zip file of this theme via the green *Code" button above.
The zip can be uploaded directly to your site via Themes in the Wordpress dashboard, then Add Theme and finally Upload Theme. If you run into size upload limits or just prefer going old school like me, unzip the package and ftp the entire folder into your wp-content/themes directory.
You can update the theme at any time by uploading a newer version through the same steps above (check the theme page for the current version).
To have your site stay up to date automatically, I recommend trying the WP Pusher plugin which makes it easier to install themes and plugins that are published in GitHub. It takes a few steps to set up, but it's a thing of beauty when done.
To use WP-Pusher you will need to have or create an account on GitHub (free). Log in.
Next download WP Pusher plugin as a ZIP file. From the plugins area of your Wordpress dashboard, click the Upload Plugin button, select that zip file to upload, and activate the plugin.
Then click the WP Pusher option in your Wordpress Dashboard, and then click the GitHub tab. Next click the Obtain a GitHub Token button to get an authentication token. Copy the one that is generated, paste into the field for it, and finally, click Save GitHub Token.
Now you are ready to install WP-Dimension!
Look under WP Pusher for Install Theme. In the form that appears, under Theme Repository, enter cogdog/wp-dimension. Also check the option for Push-to-Deploy (this will automatically update your site when the theme is updated) finally, click Install Theme.
Woah Neo?
Not only does this install the theme without any messy download/uploads, each time I update the theme on GitHub, your site will be automatically updated to the newest version.
To get the WP-Dimension active on your site all you need to do is activate the "WP-Dimension" theme when it appears in the Wordpress dashboard under Appearance --> Themes. Now you can move on to learn about setting it up in the WP-Dimension Documentation.
If you want a site that is not completely empty, after setting up with WP-Pusher or from scratch, you can import all the content set up on the public demo site.
Install all content by downloading the WordPress export for that site. Running the WordPress Importer (under Tools -- Import) and upload that file when prompted.
