-# Examples 
-### Primitive
-1. [Egoless](examples/e1_egoless.py) example.
-   + Run a SMARTS simulation without any ego agents, but with only background traffic.
-1. [Single-Agent](examples/e2_single_agent.py) example.
-   + Run a SMARTS simulation with a single ego agent.
-1. [Multi-Agent](examples/e3_multi_agent.py) example.
-   + Run a SMARTS simulation with multiple ego agents.
-1. [Environment Config](examples/e4_environment_config.py) example.
-   + Demonstrate the main observation/action configuration of the environment.
-1. [Agent Zoo](examples/e5_agent_zoo.py) example.
-   + Demonstrate how the agent zoo works.
-1. [Agent interface example](examples/6_agent_interface.py)
-   + TODO demonstrate how the agent interface works.
-
-### Integration examples
-A few more complex integrations are demonstrated.
-
-1. Configurable example
-   + script: [examples/e7_experiment_base.py](examples/e7_experiment_base.py)
-   + Configurable agent number.
-   + Configurable agent type.
-   + Configurable environment.
-1. Parallel environments
-   + script: [examples/e8_parallel_environment.py](examples/e8_parallel_environment.py)
-   + Multiple SMARTS environments in parallel

-### RL Environment
-1. [ULTRA](https://github.com/smarts-project/smarts-project.rl/blob/master/ultra) provides a gym-based environment built upon SMARTS to tackle intersection navigation, specifically the unprotected left turn.

 =====
 
-**RLlib** is an open-source library for reinforcement learning that offers both high scalability and a unified API for a variety
-of applications. ``RLlib`` natively supports ``TensorFlow``, ``TensorFlow Eager``, and ``PyTorch``. Most of its internals are agnostic to such
-deep learning frameworks.

 SMARTS contains two examples using `Policy Gradients (PG) <https://docs.ray.io/en/latest/rllib-algorithms.html#policy-gradients-pg>`_.
 
-1. ``e12_rllib/pg_example.py``
-This example shows the basics of using RLlib with SMARTS through :class:`~smarts.env.rllib_hiway_env.RLlibHiWayEnv`.
-1. ``e12_rllib/pg_pbt_example.py``
-This example combines Policy Gradients with `Population Based Training (PBT) <https://docs.ray.io/en/latest/tune/api/doc/ray.tune.schedulers.PopulationBasedTraining.html>`_ scheduling.
