How Do I Install a Boutique Demo on my WordPress?

Good morning
Here's Boutique's documentation: http://test.kutethemes.net/Boutique-Doc/. To install this theme, you should check some requirements the Boutique theme. Before you begin the install, checking to ensure that you have the minimum requirements for Boutiques WordPress 4.4.0 or highter, PHP 5.4 or highter and MySQL 5.4 or highter. Recommended PHP Configuration Limits:
Many issues that you may run into such as; white screen, demo content fails when importing, empty page content with Fusion Builder and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own, or contact your web host and ask them to increase those limits to a minimum as follows:
max_execution_time 360
memory_limit 256 M
post_max_size 64 M
upload_max_filesize 64 M
Please let me know if you need help.
