## Parameterized markdown snippets

components, writing-content

Reusable Markdown snippets support arbitrary parameters that can be used as variables in the snippet. This enables flexible, reusable content templates.

Create a snippet with parameter placeholders using curly braces:

**`fern/snippets/watering-schedule.mdx`**

```mdx fern/snippets/watering-schedule.mdx
<Warning>Remember to water your {plant} every {interval} days.</Warning>
```

Pass parameters when including the snippet:

**`page.mdx`**

```mdx page.mdx
<Warning>Remember to water your peace lily every 3 days.</Warning>

```

This renders as:

> **Warning**
>
> Remember to water your peace lily every 3 days.
