Once installed and activated, a new “WP Clone” menu item will appear in your WordPress admin sidebar.

If you click it, you'll be taken to the following screen:

And it's incredibly simple. Here's how it works ...

Obviously, first of all, you need to create a backup (a mirror package) of your existing live Wordpress website. Click the blue "Backup" button. It could take a while depending on the size of your live site.

When it's done, the "Backup" function will give you a URL that you can then copy and paste into the "Restore" dialog of your offline WAMP WordPress site, to create an exact copy of your live site:

Now you are (almost) ready to mirror your live site to your local WAMP environment. Obviously, in order to do that, first you'll have to install WP Clone on your offline Wordpress site too.

And all you have to do, is to run the "Restore" function on your local site, using the previously created backup URL:

And that's it! Your entire live website will be copied to your offline playground.

And whenever you want to update your live site after creating new content pieces, testing plugins, etc, all you have to do is to follow the same process. Vice versa of course :)
