-## Import & Embed markdown's content
+## Markdown File Inclusion
 
-When you need to combine multiple markdown content over a single markdown file, e.g.
+You can include a markdown file in another markdown file like this:
 
-```vue
-<script>
-import basics from './parts/basics.md'
-import reference from './parts/reference.md'
-</script>
+**Input**
 
+```md
 # Docs
 
 ## Basics
 
-{{ basics }}
+<!--@include: ./parts/basics.md-->
+```
 
-## API Reference
+**Part file** (`parts/basics.md`)
 
-{{ reference }}
-```
+```md
+Some getting started stuff.
 
-Replace curly brackets with `@include`, 
-the pathname with the extension, 
-surrounded by `<!-- -->` sintax
+### Configuration
 
-```vue
-<script>
-import basics from './parts/basics.md'
-import reference from './parts/reference.md'
-</script>
+Can be created using `.foorc.json`.
+```
+
+**Equivalent code**
 
+```md
 # Docs

-< !--@include:./parts/basics.md-->
