+# Generate data with expert policies
+
+## Expert Policies
+For each individual environment in Meta-World (i.e. reach, basketball, sweep) there are expert policies that solve the task. These policies can be used to generate expert data for imitation learning tasks.
+
+## Using Expert Policies
+The below example provides sample code for the reach environment. This code can be extended to the ML10/ML45/MT10/MT50 sets if a list of policies is maintained.
+
+
+```python
+from metaworld import MT1
+
+from metaworld.policies.sawyer_reach_v2_policy import SawyerReachV2Policy as p
+
+mt1 = MT1('reach-v2', seed=42)
+env = mt1.train_classes['reach-v2']()
+env.set_task(mt1.train_tasks[0])
+obs, info = env.reset()
+
+policy = p()
+
+done = False
+
+while not done:
+    a = policy.get_action(obs)
+    obs, _, _, _, info = env.step(a)
+    done = int(info['success']) == 1
+
+
+```
