How to Add Header and Footer in Grav CMS

I know how to add content in Grav CMS but i am facing problem in how to add a header section in Grav CMS. Please tell me where do i have to write the code for header and footer. In (.md) files or twig files?

As domsson already noted, there are more than a single way to do it in Grav

1. You can check implementation of it in (default) [Quark theme][1]:
`templates/partials/base.html.twig`, which is used by all other templates, have in needed location `{% include 'partials/footer.html.twig' %}` and `footer.html.twig`, in turn, contain all needed data for rendering on page

2. You can also see (use) idea from [Open Publishing Space skeleton][2]

` {# display footer markdown page - hibbittsdesign.org #}
{% set content = pages.find('/footer').content %}
{% if content %}
{{ content|raw }}
{% endif %}`

Here ordinary page (/footer) from site (editable as much as needed) used instead of template and have anything in it, it's content used as site-footer

3. If you have site with modular-pages only (like, f.e. [Deliver skeleton][3]), you can also (except using base-template as per p.1) add to **all** modular-collections

` content:
items: @self.modular
…`

page, which share common template (and data)
