8. Press Conversion and successful link to see preview of this page.
   
   
9.  At the bottom of the page you will see a Yellow Box that represents the place holder where dynamic content is going to be inserted. We're going to now move that place holder into where we want it to replace our dummy text in the middle of the page.
   
10. Download the HTML file from the Share Point 2013 environment and open it in your HTML editor and you will see that Share Point 2013 has decorated your HTML with a number of tags.  These tags are used by Share Point 2013 as markup to specify where to put to insert content when it generates the Master Page. 
11. Publish HTML file it will reflect automatically in master file.
