How to install a Joomla template

Login the back-end on your site (www.yourdomain.com/administrator).

Click on Extensions > Manage > Install

There are several different ways to install a Joomla template from here. You can install your Templates, Plugins, Modules, Components and Languages. You have four options:

1. Install from Web - (select an extension listed on the Joomla! Extension Directory)
2. Upload Package File - (select a package from your PC, upload and install it)
3. Install from Directory - (enter the path where the package is located on your webserver)
4. Install from URL - (enter the URL to the package)

Here we choose the second method: Upload Package File

Select the package from your PC and click the button Upload & Install

If the package contains no errors you are done and get a success message like the one below.
