+At the top level of a template that receives the `Site` object in context, these are equivalent:
+
+```go-html-template
+{{ .Site.Params.foo }}
+{{ site.Params.foo }}
+```
+
+When the `Site` object is not in context, use the global `site` function:
+
+```go-html-template
+{{ site.Params.foo }}
+```
+
+{{% note %}}
+To simplify your templates, use the global `site` function regardless of whether the `Site` object is in context.
