Jekyll Bootstrap uses site.pages
and loops through them to create the Top Nav.
So to add your Resume to that list, you need to do this:
Assuming your Resume is here: Jekyll Bootstrap Root Directory -> /resume/index.md
.
At the top of /resume/index.md
add this single line group: navigation
to your YAML Front Matter after your title
:
---
layout: page
title: Resume
group: navigation
---
See this file in JB, which explains:
https://github.com/plusjade/jekyll-bootstrap/blob/master/_includes/JB/pages_list
EDIT: Oh, I see you are using /resume.md
and /resume/index.md
for the same content. So add the group: navigation
line to the one which you want in the main nav, but not both.
