+This rule identifies several problems related to the naming of tasks and plays.
+This is important because these names are the primary way to **identify** and
+**document** executed operations on console, logs or web interface.
 
 This rule can produce messages such:
 
-- `name[casing]` - All names should start with an uppercase letter.
+- `name[casing]` - All names should start with an uppercase letter for
+  languages that support it.
 - `name[missing]` - All tasks should be named.
 - `name[play]` - All plays should be named.
 
+If you want to ignore some of the messages above, you can add any of them to
+the `ignore_list`.
+
 ### Problematic code
 
 ```yaml
 ---
-- hosts: localhost
+- hosts: localhost # <-- playbook missing a name key
   tasks:
-    - ansible.builtin.command: touch /tmp/.placeholder
+    - name: create placefolder file # <-- not starting with a capital letter
+      ansible.builtin.command: touch /tmp/.placeholder
 ```
