+Each default page is a template with its own content saved into a record. This is the reason why,

 .. code-block:: xml
 
-   <t t-set="additional_title" t-value="'...'"/>
+   <t t-set="additional_title">My Page Title</t>
+
+.. tip::
+   The `t-set` here does not pass the value into a `t-value` or a `t-valuef` attribute.
+   This is for translation purpose. The content of a `t-value` or a `t-valuef` is not explicitly
+   exported for translation. Beside that, as it's written in XML, a string located between an opening
+   and a closing tag is considered translatable by default.
+
+   .. example::
+      **Good example:**
+
+      .. code-block:: xml
+
+         <t t-set="additional_title">My title</t>
+
+      **Bad example:**

+      <!-- Your record -->
+   </data>
+
+**Use case**
+
+There are several static pages created in the module. This one has been installed on the database
+and the end-user has updated some of those pages. Some bug fixes must be applied on the
+static pages while avoiding any loss of changes made by the end-user.
+
+**Problem**
+
+In case of a module update on the database, every record declared into the module will overwrite
+those existing in the database even if the end-user has changed some of these records.
+
+**Solution**
+
+By wrapping the record (or all records declared in the file) into a `<data noupdate="1"></data>`
+tag, the record declared is created at
+the first module installation but not updated after a module update.
+
+.. spoiler:: What happens if the record has been manually deleted (e.g.: a menu item) ?
+
+   The system detects that this record doesn't exist and will re-create it.

+
+   Of course not. It's technically usable for every type of records.
