     - we have decided to create a new structure file :file:`firefox/20-manual.yml`. 
       This is not necessary but usefull, please have a look at the :ref:`structure file organization and naming conventions <namingconvention>`
 
+Let's switch this boolean variable to a `false` value:

+We could of course perform several tests on type validators, but here the validation is simple: only two values ​​are allowed (`true` or `false`).
 
 .. keypoints:: let's review the key points
 
     - we can assign a `domainname` type to a variable
     - we can set a :term:`parameter` to a `domainname` variable to refine their typing behavior
     - we can assign a `port` type to a variable
+    - we know how to set a `boolean` type variable to `true` or `false`
