 class Individual(object):
-    """
-    Class for an individual.
+    """A class representing an individual agent in a queueing network simulation.
+
+    An Individual instance models the flow of an agent through a queueing network, tracking its arrival time, service time, priority, and other relevant data. This class provides a framework for simulating and analyzing the behavior of such agents.
+
+    Parameters
+    ----------
+    id_number : int
+        A unique identifier for the individual.
+    customer_class : str, optional
+        The customer class to which the individual belongs (default is 'Customer').
+    priority_class : int, optional
+        The priority class of the individual (default is 0).
+    simulation : bool, optional
+        A flag indicating whether the individual is part of a simulation (default is False).
+
+    Attributes
+    ----------
+    arrival_date : bool
+        Timestamp for the arrival of the individual.
+    service_start_date : bool
+        Timestamp for the start of service for the individual.
+    service_time : bool
+        Time taken for the service.
+    service_end_date : bool
+        Timestamp for the end of service for the individual.
+    exit_date : bool
+        Timestamp when the individual exits the system.
+    id_number : int
+        Unique identifier for the individual.
+    data_records : list
+        A list to store additional data records.
+    customer_class : str
+        The customer class to which the individual belongs.
+    previous_class : str
+        The previous customer class of the individual.
+    priority_class : int
+        The priority class of the individual.
+    prev_priority_class : int
+        The previous priority class of the individual.
+    original_class : str
+        The original customer class of the individual.
+    is_blocked : bool
+        Indicates if the individual is blocked.
+    server : bool
+        Indicates whether the individual is assigned to a server.
+    queue_size_at_arrival : bool
+        Size of the queue at the time of arrival.
+    queue_size_at_departure : bool
+        Size of the queue at the time of departure.
+    destination : bool
+        The destination node in the network.
+    interrupted : bool
+        Indicates if the individual's service was interrupted.
+    node : bool
+        The node in the network where the individual is located.
+    simulation : bool
+        A flag indicating whether the individual is part of a simulation.
+
+    Methods
+    -------
+    __repr__()
+        Returns a string representation of the individual as 'Individual <id_number>'.
+
+    Usage
+    -----
+    You can create and manipulate instances of the Individual class to simulate and study the behavior of agents within a queueing network.
+
+    Example
+    -------
+    ```
+    individual = Individual(id_number=1, customer_class='Gold', priority_class=1, simulation=True)
+    ```
+
+    For more details on the attributes and methods, please refer to the class documentation.
