-```go-html-template
-{{ $var := "foo" }}
-{{ with $var }}
-  {{ . }} → foo
-{{ end }}
-```
-
-Use with the [`else`] statement:
-
-```go-html-template
-{{ $var := "foo" }}
-{{ with $var }}
-  {{ . }} → foo
-{{ else }}
-  {{ print "var is falsy" }}
-{{ end }}
-```
-
-Initialize a variable, scoped to the current block:
-
-```go-html-template
-{{ with $var := 42 }}
-  {{ . }} → 42
-  {{ $var }} → 42
-{{ end }}
-{{ $var }} → undefined
-```
-
-## Understanding context
-
-At the top of a page template, the [context] (the dot) is a `Page` object. Inside of the `with` block, the context is bound to the value passed to the `with` statement.
-
-With this contrived example:
-
-```go-html-template
-{{ with 42 }}
-  {{ .Title }}
-{{ end }}
-```
-
-Hugo will throw an error:
-
-    can't evaluate field Title in type int
-
-The error occurs because we are trying to use the `.Title` method on an integer instead of a `Page` object. Inside of the `with` block, if we want to render the page title, we need to get the context passed into the template.
-
-{{% note %}}
-Use the `$` to get the context passed into the template.
-{{% /note %}}
-
-This template will render the page title as desired:
-
-```go-html-template
-{{ with 42 }}
-  {{ $.Title }}
-{{ end }}
-```
-
-{{% note %}}
-Gaining a thorough understanding of context is critical for anyone writing template code.
