 A minimal example
 -----------------
 
-This minimal model represents a single project activity that requires one crew.
-The activity waits until the crew is available, performs the work, and then releases
-the resource. The SimPM engine models activities with ``do`` (time spent working)
-and ``get`` / ``put`` (queueing for and releasing resources), rather than raw
-``timeout`` calls.

+This minimal model represents a single project activity that requires one crew.  
+The activity waits until the crew is available, works for a random duration, and then finishes.
 This example shows how to:
 
 - Create a :class:`simpm.des.Environment`
 - Define a simple :class:`simpm.des.Resource`
-- Model work with :class:`simpm.des.Entity` using ``do`` and ``get``
-- Run the simulation and inspect basic outputs
+- Run the simulation
+- Inspect basic outputs (duration and finish time)
 
 .. code-block:: python
 
-   import simpm
    from simpm.des import Environment, Resource
    from simpm.dist import norm
 
    # 1) Create the simulation environment
-   env = Environment("Single activity")
+   env = Environment()
 
    # 2) Define resources (e.g., one crew)
-   crew = Resource(env, name="Crew 1", capacity=1)
-
-   # 3) Create an entity to perform the activity
-   (activity_entity,) = env.create_entities("Activity", 1, print_actions=False, log=True)
+   crew = Resource(env, capacity=1, name="Crew 1")
 
-   # 4) Define the activity process
-   def activity(entity, resource):
+   # 3) Define an activity process
+   def activity(env, resource, name):
        # Request one unit of the crew resource and wait until it is available

+       yield resource.request()
 
        # Perform the work
        duration = norm(10, 2).sample()
-       yield entity.do("work", duration)
-
-       # Release the crew
-       yield entity.put(resource, 1)

+       print(f"{env.now:.2f}: {name} finished (duration={duration:.2f})")
 
-   env.process(activity(activity_entity, crew))
+   # 4) Create entities / activities
+   env.process(activity(env, crew, "Activity A"))
 
    # 5) Run the simulation
