-Rendering `a2.tmpl` will output `From A1: Want-this-to-be-skipped`. The text `Want-this-to-be-included.` is rendered because the `super()` call render as the text from the parent template into the block, which will then be substitute into topmost template.
+Rendering ``child.tmpl`` will give
+``body: Hi from child. Hi from parent.``
 
-Rendering `a3.tmpl` will output `From A1: Some Text`. We substitute the block text into the parent template.
+Rendering ``grandchild1.tmpl`` will give
+``body: Hi from grandchild1.``
 
-Rendering `a4.tmpl` will output `From A1: From A4: Want-this-to-be-included.` Here, we are accessing the `super` property from the `super` object to get access to the text in grandparent's block. Had we just done `super()`, this would have returned `From A1: From A4: Want-this-to-be-skipped. Want-this-to-be-included.`.
+Rendering ``grandchild2.tmpl`` will give
+``body: Hi from grandchild2. Hi from parent.``
