 Use the Brain class directly, rather than a subclass. Brain behavior is determined by the **Brain Type**. ML-Agents defines four Brain Types:
 
-* [External](Learning-Environment-External-Internal-Brains.md) — The **External** and **Internal** types typically work together; set **External** when training your agents. You can also use the **External** brain to communicate with a Python script via the Python `UnityEnvironment` class included in the Python portion of the ML-Agents SDK.
-* [Internal](Learning-Environment-External-Internal-Brains.md) – Set **Internal**  to make use of a trained model.
-* [Heuristic](Learning-Environment-Heuristic-Brains.md) – Set **Heuristic** to hand-code the agent's logic by extending the Decision class.
-* [Player](Learning-Environment-Player-Brains.md) – Set **Player** to map keyboard keys to agent actions, which can be useful to test your agent code.

 During training, set your agent's brain type to **External**. To use the trained model, import the model file into the Unity project and change the brain type to **Internal**.

 - **Reset : `env.reset(train_model=True, config=None)`**  
 Send a reset signal to the environment, and provides a dictionary mapping brain names to BrainInfo objects.  
     - `train_model` indicates whether to run the environment in train (`True`) or test (`False`) mode.
-    - `config` is an optional dictionary of configuration flags specific to the environment. For more information on adding optional config flags to an environment, see [here](Making-a-new-Unity-Environment.md#implementing-yournameacademy). For generic environments, `config` can be ignored. `config` is a dictionary of strings to floats where the keys are the names of the `resetParameters` and the values are their corresponding float values.

Define the reset parameters on the [Academy Inspector](Learning-Environment-Design-Academy.md#academy-properties) window in the Unity Editor.
 - **Step : `env.step(action, memory=None, text_action=None)`**  
 Sends a step signal to the environment using the actions. For each brain : 
     - `action` can be one dimensional arrays or two dimensional arrays if you have multiple agents per brains.
