# brand.yml extension

Here is some inline code: `def foo(x): return x`{.python} and `y`{.python} and `z`{.python}.

Here is [a link](https://example.com).

Here is a code block:

```{.r}
# | echo: true
fibonacci <- function(n) {
  if (n <= 0) {
    return(NULL)
  } else if (n == 1) {
    return(0)
  } else if (n == 2) {
    return(1)
  } else {
    return(fibonacci(n - 1) + fibonacci(n - 2))
  }
}
```
