 ### Run and get results
 
 Now that you have defined your `estimator`, you can run your estimation by calling the [`qiskit.primitives.Estimator.run`](../api/qiskit/qiskit.primitives.Estimator#run) method,
-which returns an instance of [`qiskit.providers.JobV1`](../api/qiskit/qiskit.providers.JobV1). You can get the results from the job (as a [`qiskit.primitives.EstimatorResult`](../api/qiskit/qiskit.primitives.EstimatorResult) object)
+which returns an instance of [`qiskit.providers.JobV1`](../api/qiskit/qiskit.providers.JobV1). 
+
+The V2 primitives take one or more primitive unified blocs (PUBs) as the inputs. Each PUB is a tuple that contains a single circuit and data broadcasted to that circuit.

 This example only uses one [`qiskit.circuit.QuantumCircuit`](../api/qiskit/qiskit.circuit.QuantumCircuit) and one observable. If you want to get expectation values for multiple circuits and observables, you can pass a `list` of [`qiskit.circuit.QuantumCircuit`](../api/qiskit/qiskit.circuit.QuantumCircuit)s and a list of `BaseOperator`s to the [`qiskit.primitives.Estimator.run`](../api/qiskit/qiskit.primitives.Estimator#run) method. Both `list`s must have the same length.
 
 #### Get the expected value
