+# Exploration Policy
+
+An exploration policy is a module that is responsible for choosing the action according to the action values, the
+current phase, its internal state and the specific exploration policy algorithm.
+
+A custom exploration policy should implement both the exploration policy class and the exploration policy parameters
+class, which defines the parameters and the location of the exploration policy module.
+The parameters of the exploration policy class should match the parameters in the exploration policy parameters class.
+
+Exploration policies typically have some control parameter that defines its current exploration state, and
+a schedule for this parameter. This schedule can be defined using the Schedule class which is defined in
+exploration_policy.py.
+
+A custom implementation should look as follows:
+
+```
+class CustomExplorationParameters(ExplorationParameters):
+    def __init__(self):
+        super().__init__()
+        ...
+
+    @property
+    def path(self):
+        return 'module_path:class_name'
+
+
+class CustomExplorationPolicy(ExplorationPolicy):
+    def __init__(self, action_space: ActionSpace, ...):
+        super().__init__(action_space)
+
+    def reset(self):
+        ...
+
+    def get_action(self, action_values: List[ActionType]) -> ActionType:
+        ...
+
+    def change_phase(self, phase):
+        ...
+
+    def get_control_param(self):
+        ...
+```
