On occasion, you may want to re-purpose an existing SharePoint 2013 site. Creating a site template allows you to create new sites based off the template. You can choose to either include existing content or to simply use the site's structure.   

Go to Site Settings > Save site as template


Name your template and indicate whether or not you want to include the content or just save the structure


Then press OK

It DOES take a little while so don't be concerned

Creating a new site from a site template

 Go to the site contents of the site where you want to create this site and click new subsite

Name your site and under the template section choose the Custom tab and then choose the template that you just saved.


As with any site creation, choose the permissions and navigation, then click Create

That's all there is to it!!
