As we know Koha OPAC can be turned into a tiny library website or it can act as a Content Management System making changes on the page.pl file. Detailed documentation for creating Koha as a CMS is available at Koha Wiki. Here is a little tip for adding custom links on the OPAC Breadcrumb.
Go to the opac-main.tt
sudo gedit /usr/share/koha/opac/htdocs/opac-tmpl/bootstrap/en/modules/opac-main.tt
Add your page links below
<ul class="breadcrumb">
Eg: <li><a href="http://127.0.1.1/pages.pl?p=about-us">About Us</a>
[% IF news_item %]
<span class="divider">›</span></li>
<li>[% news_item.title | html %]</li>
[% END %]
</li>
Result
Thank You...
