For downloading your current template, click on the Download full template button:

1. Edit the Main Navigation Menu
Go to Blogger, select Template > click on Edit HTML button and search for the html code below (press CTRL + F keys). After you found it, replace 'Link URL' (without the quotes) to the ULR/address of the link that you want to target, also change the title of the link.
<li><a href='Link URL'>Title 1</a></li>Change these lines as well:
<li><a href='Link URL'>Title 2</a></li>If you want to add another link, then simply paste this code just below the last line:
<li><a href='Link URL'>Title 3</a></li>
<li><a href='Link URL'>Title 4</a></li>
<li><a href='Link URL'>Title 5</a></li>
<li><a href='Link URL'>Title 6</a></li>
