Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.

{% set context fromYourYamlFile %}
- or -
{% set context = { 
"component-type" : "container",
"id" : "an-id-for-anchor",
"vf_intro_heading" : "Transversal research themes",
"vf_intro_badge" : [object Object],
"vf_intro_subheading" : "Understanding life in the context of its environment",
"vf_intro_lede" : "EMBL’s future directions will be driven by the goal of understanding life in the context of its environment. While the effects of the environment on living systems have been well studied at the level of individual organisms and populations, many of the underlying molecular processes remain obscure.",
"vf_intro_text" : We now have the tools and technologies to explore these processes, allowing us to understand life in its natural context from the level of molecules to whole ecosystems. This new understanding will be critically important if we are to tackle societal challenges such as environmental degradation and loss of biodiversity, climate change, and threats to human health such as the emergence of new epidemics.,EMBL’s new transversal research themes will enable us to realise this vision of understanding life in context. The transversal research themes will be highly interdisciplinary and will encourage dynamic internal and external collaborations. These themes will enable transformative discoveries by bringing together experts in fields such as ecology, epidemiology, toxicology, zoology, population genetics, engineering, and mathematical theory. There will be strong support for building collaborations within each theme, as well as with the wider scientific community, not only to enable scientific discovery but also to build these themes across the EMBL sites.,
 }
%}
{% include "../path_to/vf-intro/vf-intro.njk" %}
                

Using render

This approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.

{% render '@vf-intro', {
  "component-type" : "container",
  "id" : "an-id-for-anchor",
  "vf_intro_heading" : "Transversal research themes",
  "vf_intro_badge" : [object Object],
  "vf_intro_subheading" : "Understanding life in the context of its environment",
