Creating navbar links with the default markata templates is done by adding
links in your markata.toml configuration within a markata.nav block.
Example
The following example will create two links, one to the root of the site, with
the text markata and one to the github repo for markata with the text of
GitHub.
[markata.nav]
'markata'='/'
'GitHub'='https://github.com/WaylonWalker/markata'
Result
The resulting navbar would look something like this.
In your own template
If you want to continue using this method of maintaining your nav links with a custom template, add this block to your template where you want your nav to appear.
<nav>
<a href='/'>markata</a>
<a href='https://github.com/WaylonWalker/markata'>GitHub</a>
</nav>
