 The post summary is taken from the first part of the article. If you add a `<-- more -->` tag, everything before that will be treated as the post summary.
 
+## Attach files to an article
+
+As previously explained, every article has its own folder. Any file you place inside that is not a Markdown file will be copied alongside the generated page. [Asset colocation](https://www.getzola.org/documentation/content/overview/#asset-colocation) is further discussed in the Zola documentation.

+This means you can directly link the file from the Markdown page using a relative link:
+
+```

+
+## Link another page from an article
+
+A link to another page in Markdown can use the @ sign to signify the link target is found in the content folder, as explained in the docs on [internal links](https://www.getzola.org/documentation/content/linking/#internal-links):
+
+```
++++

 Adding a language is not hard, but it takes a few steps. The example here takes `fr` as language code for french translations, just replace it with your own language.

 Warning: don't forget to copy the placeholder section file for year-folders in the blog, otherwise no article will appear on your language's blog. You can safely copy content/2020/_index.md to, say, content/2020/_index.fr.md.
 
+## Use translations in the templates
+
+### Localized string
+
+If you want to use a translation define in the translations section of the config, you can use the [trans](https://www.getzola.org/documentation/templates/overview/#trans) function, like so:
+
+```
+{{ trans(key="readmore", lang=lang) }}
+```
+
+The lang variable is conveniently set for you at the top of index.html template so all templates which extend index.html should have it.
+
+### Localized path
+
+In case you need to interact with a localized page, you will need to replace the last .md with .LANG.md. There is a small macro called i18n_path for this in widgets.html. You can use it like this:
+
+```
+{% import "widgets.html" as widgets %}
+{{ widgets::i18n_path(path="@/blog/_index.md") }}
+```
+
+It will automatically use the language code figured out in index.html.
+
+### Localized page content
+
+If you wish to directly extract the contents of a localized page, without any regards to its frontmatter, you can use the i18n_content macro:
+
+```
+{% import "widgets.html" as widgets %}
+{{ widgets::i18n_content(path="@/blog/_index.md") }}
+```
