+---------
 
-The default mode of the leader family is the mode of the leader variable.

-
-Leader variable
-----------------
-
-A leader variable is a variable that will guide the length of other variables (called follower variables).
-
-A leader variable is a :doc:`variable` that must have the `multiple` type.
-
-A leader variable may be mandatory.
-
-The default mode corresponds to the smallest mode defined for the follower variables.
-
-Follower variable
---------------------
-
-A follower variable is a variable whose length is not determined by itself, but is identical to that of the leader variable on which it depends.
-
-A follower variable is a variable placed just behind a leader variable or another follower variable.
-
-The order in which the tracking variables are defined is important.
-
-This variable can be of multiple type. In this case, for a determined index of the leading variable, it is possible to put several values to the same variable.
-
-A follower variable may be required. This means that when a leader variable is entered, the follower variable must also be a value at the index considered. If no value is defined for the leader variable, no value is specified for the follower variable.
-
-The default mode of a follower variable corresponds to the mode of the leader variable.
-
-If a leader variable is hidden or disabled, the follower variables will be hidden or disabled as well.

-      help: This is the help of a great family
+      help: This family is great because we have great variables inside

+   You can have a look at the tutorial with a real world sample:
+
+   - :ref:`family <tutorial/family>`
+   - :ref:`help parameter <tutorial/examples>` (the tutorial focuses on variable, but the principle is the same for a family)
+
+A dynamically built family
+-----------------------------
+
+To create a family dynamically, you must create a fictitious family linked to a list of uniq identifiers.
+This list could be hard coded or resulting from a calculation
+
+In this case if the result of calculation were to evolve, new dynamic families will appear or disappear.
+
+The name of this family is particular. You have to add `{{ identifier }}` string inside. It will be replace by each identifiers.
+
+Here is an simple example:
 
 .. code-block:: yaml
 
+    %YAML 1.2
     ---
-    version: '1.1'
+    version: 1.1
-    varname:
+    
-      multi: true
+    my_{{ identifier }}_family:
-      default:
+      description: 'A family for {{ identifier }}'
-        - val1
-        - val2
-    my_dyn_family_:
-      type: dynamic
       dynamic:
-        type: variable
+        - one thing
-        variable: rougail.varname
+        - another
-      description: 'Describe'
+
-      my_dyn_var:
+      variable:
-        type: string
+        description: 'A variable for {{ identifier }}'
-        description: 'Variable description'
+    ...
 
 This will dynamically create two families:
 
-- "rougail.my_dyn_family_val1"
+- "my_one_thing_family"
-- "rougail.my_dyn_family_val2"
+- "my_another_family"
 
-In the dynamic family "rougail.my_dyn_family_val1" we will find a variable "my_dyn_var".
+.. seealso::
 
-Here is a second example:
+   You can have a look at the tutorial with a real world sample :ref:`dynamically built family <tutorial/dynfam>`
+
+Similar object sequence
+-------------------------
+
+A family with `type` set to `leadership` is a sequence of similar object.
+
+Let's start the explanation with a concrete example:
 
 .. code-block:: yaml
 
+   %YAML 1.2
    ---
-    version: '1.1'
+   version: 1.1
-    varname:
-      multi: true
-      default:
-        - val1
-        - val2
-    my_dyn_{{ suffix }}_family:
-      type: dynamic
-      dynamic:
-        type: variable
-        variable: rougail.varname
-      description: 'Describe'
-      my_dyn_var:
-        type: string
-        description: 'Variable description'
 
-This will dynamically create two families:
+   accounts:
-
+     description: All accounts
-- "rougail.my_dyn_val1_family"
-- "rougail.my_dyn_val2_family"
-
-In the dynamic family "rougail.my_dyn_val1_family" we will find a variable "my_dyn_var".
-
-Leader or follower variable
--------------------------------
-
-Definition of leader and follower variables
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Here is an example of defining a leading variable and two following variables:
-
-.. code-block:: yaml
-
-    ---
-    version: '1.1'
-    family:
      type: leadership
-      leader:
-        multi: true
-      follower1:
-      follower2:
-        multi: true
 
-Adding a new follower variable
+     login:
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+       description: Account login
+       type: unix_user
 
-To add a new follower variable, in a new dictionary, simply define one or more new variables in the leader family:
+     secret:
+       description: Account secret
+       type: secret
+   ...
+
+What is expected, it's something like:
 
 .. code-block:: yaml
 
     ---
-    version: '1.1'
+    accounts:
-    family:
+      - login: foo
-      follower3:
+        secret: 0hM%G0dW4a7ASecr3t
+      - login: bar
+        secret: NotGoodSecret
+
+It's what we call a sequence of similar object.
+
+.. attention:: A sequence cannot contain other families.
+
+.. seealso::
+
+   You can have a look at the tutorial with a real world sample :ref:`similar object sequence <tutorial/sequence>`
+
+A custom type family
+----------------------
+
+In short, a custom type is nothing more than a kind of a template for a family.
+Define a custom type family is much like defining families.
+
+This custom type family can be used as many times as desired and customized as you wish.
+
+.. seealso::

+
+    - It is possible to retrieve the current state of the various Rougail files manipulated in this tutorial step

+      Each tag corresponds to a stage of progress in the tutorial.

+The variable "type" that conflit with the family attribute "type"
+---------------------------------------------------------------------
+
+Choice a good variable name is important. It's with this name that user will interact with here value.
+
+The user has to define the type of the new proxy. So instinctively the name of the variable will be `type`.
+
+But in the current family we have already the attribute `type` with the `leadership` value.
+YAML do not permit to have two key with the same name.
+Maybe we could choice an other variable name like `proxy_type` but the full path will be `proxies.proxy_type`.
+Repeating the word proxy is not appropriate.
+
+So the best way it to rename the `type` attribute to `_type`
+
+Let's create a family named `manual` which obviously corresponds to the proxy's manual configuration choice.
