The header menu is the set of links on the bottom edge of the black banner on the top part of the page. It can be an internal link to a certain page in your website that is often visited, an external link to another website, or a button to switch the content language.

Internal links
The most basic way to add a new header menu is to add a new parameter block menu.header in the config.toml. Suppose you want to add a header menu entry for the content at /URL, you should add
[[menu.header]]
name = "DISPLAYED NAME"
url = "/URL"
weight = 1
where the weight specifies the order of the header menu when there are multiple entries.
External links
You can also add external links with small banners. Add a new parameter block Params.exlink in the config.toml:
[[Params.exlink]]
url = "LINK"
pass = "PATH TO IMAGES"
Language-switch button
The link for switching languages is created by the parameter block Languages.**.params:
[Languages.en]
weight = 1
[Languages.en.params]
Language_name = "English"
The weight corresponds to the order in which the languages are placed, and the Language_name is the string that is displayed for the language. See also Going global for an example.
