In addition to the default theme included with your WordPress installation, you can  also install your own WordPress theme to change the look and style of your site.

How to Install a WordPress Theme from on Vimeo.

Download & Upload Method

  1. From the WordPress dashboard, expand the Appearance menu in the  left hand navigation panel. Click the Themes link.
  2. Click the Add New button
  3. Click the Upload Theme button, locate your theme zip file and then click  Install Now. Then, click Activate.

Search & Install Method

Much like installing plugins, you can search for a free theme and install it directly  from your WordPress dashboard.
  1. From the Appearance > Themes page , click on the Add New button. You  can search the Free Theme Directory right from your WordPress dashboard. Find a theme you like (you can use the search box or the feature filter to sort by various options)
  2. Once you find a theme you like, click Install. Once the theme is installed, just  click the Activate button. And just like that, your site has a brand new look.

Manual Method

You can also add themes by manually uploading them to your server with FTP  software. This is more complicated and not for the novice user. 

You’ll need to download a theme to your computer and unzip it. This will give you a folder on your computer with all the theme files. Then, using an FTP program, upload the theme folder to the wpcontent/themes folder on your site. 

Then go to the Themes screen in your dashboard and you will see your new theme  in the list. 

Click Activate to get started.

Managing Your WordPress Themes

  1. To manage your WordPress themes, expand the Appearance menu in the  WordPress Dashboard.
  2. Here, you’ll see the Themes page.
  3. The very first theme listed on this page is your Active theme. Here we also  see an option to Customise. If you click this button, you’ll see a preview window that allows you to make stylistic changes to your site, such as your Site Identity (Site Title, Tagline & Site Icon). From here, you can also make changes to Menus and the Front Page.
  4. If you return back to the Themes page, you’ll see a grid list of available  themes in addition to your active theme. These are themes that have been also installed on your WordPress site, but aren’t active.
  5. In the left-hand panel of the preview window, you can edit the theme settings.  These settings will differ, depending on what theme features the theme supports.
  6. To accept the new settings and activate the theme all in one step, click the  Save & Activate button at the top of the left-hand panel.
