+    Added minimal working code examples to the API pages for each experiment, especially in characterizaion experiments.
+    The minimal working code example is a code snippet which users can copy and paste to run the experiment.
+    Users are required to specify a backend in the code example. As a default, the backend is a simulator such as
+    GenericBackendV2(num_qubits=27). In some experiments, the backend is an IBM real device due to the
+    backend.defaults() dependence of the code example.
