This tutorial explains how to set your home page in the forums breadcrumbs.

NOTE: This tutorial is only for phpBB3.

Firstly login to your forums administrator panel and to go Styles -> Templates -> Click on the Edit link right next to the template that is currently in use -> Select breadcrumbs.html from the drop down menu.

Now find the code:

<p class="breadcrumbs"><a href="/{U_INDEX}" mce_href="/{U_INDEX}">{L_INDEX}</a> <!-- BEGIN navlinks --> » <a href="/{navlinks.U_VIEW_FORUM}" mce_href="/{navlinks.U_VIEW_FORUM}">{navlinks.FORUM_NAME}</a><!-- END navlinks --></p>

You need to insert some code so it should look like this:

<p class="breadcrumbs"> <a href="http://www.YourWebSite.com" mce_href="http://www.YourWebSite.com">YourWebSite.com</a> » <a href="/{U_INDEX}" mce_href="/{U_INDEX}">{L_INDEX}</a><!-- BEGIN navlinks --> » <a href="/{navlinks.U_VIEW_FORUM}" mce_href="/{navlinks.U_VIEW_FORUM}">{navlinks.FORUM_NAME}</a><!-- END navlinks --></p>

Of-course you need to change YourWebSite.com with the domain name of your website.

Once this is done click on the Submit button and it's done!
