+The `.Param` method on `.Page` looks for the given `KEY` in page parameters, and returns the corresponding value. If it cannot find the `KEY` in page parameters, it looks for the `KEY` in site parameters. If it cannot find the `KEY` in either location, the `.Param` method returns `nil`. 
+
+Site and theme developers commonly set parameters at the site level, allowing content authors to override those parameters at the page level.
+
+For example, to show a table of contents on every page, but allow authors to hide the table of contents as needed:
+
+**Configuration**
+
+{{< code-toggle file="hugo" copy=false >}}
+[params]
+display_toc = true
+{{< /code-toggle >}}
+
+**Content**
+
+{{< code-toggle file="content/example.md" fm=true copy=false >}}
+title = 'Example'
+date = 2023-01-01
+draft = false
+display_toc = false
+{{< /code-toggle >}}
+
+**Template**
+
+{{< code file="layouts/_default/single.html" copy=false >}}
+{{ if .Param "display_toc" }}
+  {{ .TableOfContents }}
+{{ end }}
+{{< /code >}}
+
+The `.Param` method returns the value associated with the given `KEY`, regardless of whether the value is truthy or falsy. If you need to ignore falsy values, use this construct instead:
+
+{{< code file="layouts/_default/single.html" copy=false >}}
+{{ or .Params.foo site.Params.foo }}
+{{< /code >}}
