You can now edit the override and tweak it however you prefer.

## Usage of the `hreflang` partial

A second template is available for `hreflang` annotations in the header of the page. In order to emit language annotations for the available languages of a page you need to add the corrsponding Twig partial template into the `<head>` section of your page, which can typically be found in `base.html.twig`:

```
{% include 'partials/langswitcher.hreflang.html.twig' %}
```

This will generate something like:

```
<link rel="alternate" href="http://example.com/en" hreflang="en" />
<link rel="alternate" href="http://example.com/de" hreflang="de" />
<link rel="alternate" href="http://example.com/zh-cn" hreflang="zh-cn" />
```

# Updating

As development for the LangSwitcher plugin continues, new versions may become available that add additional features and functionality, improve compatibility with newer Grav releases, and generally provide a better user experience. Updating LangSwitcher is easy, and can be done through Grav's GPM system, as well as manually.
