+# Fancy Gym
 
-| :exclamation: Fancy Gym has recently received a major refactor, which also updated many of the used dependencies to current versions. The update has brought some breaking changes. If you want to access the old version, check out the [legacy branch](https://github.com/ALRhub/fancy_gym/tree/legacy). Find out more about what changed [here](https://github.com/ALRhub/fancy_gym/pull/75). |
-| --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-
-Built upon the foundation of [Gymnasium](https://gymnasium.farama.org/) (a maintained fork of OpenAI’s renowned Gym library) `fancy_gym` offers a comprehensive collection of reinforcement learning environments.
-
-**Key Features**:
-
-- **New Challenging Environments**: `fancy_gym` includes several new environments (Panda Box Pushing, Table Tennis, etc.) that present a higher degree of difficulty, pushing the boundaries of reinforcement learning research.
-- **Support for Movement Primitives**: `fancy_gym` supports a range of movement primitives (MPs), including Dynamic Movement Primitives (DMPs), Probabilistic Movement Primitives (ProMP), and Probabilistic Dynamic Movement Primitives (ProDMP).
-- **Upgrade to Movement Primitives**: With our framework, it's straightforward to transform standard Gymnasium environments into environments that support movement primitives.
-- **Benchmark Suite Compatibility**: `fancy_gym` makes it easy to access renowned benchmark suites such as [DeepMind Control](https://deepmind.com/research/publications/2020/dm-control-Software-and-Tasks-for-Continuous-Control) and [Metaworld](https://meta-world.github.io/), whether you want to use them in the regular step-based setting or using MPs.
-- **Contribute Your Own Environments**: If you're inspired to create custom gym environments, both step-based and with movement primitives, this [guide](https://gymnasium.farama.org/tutorials/gymnasium_basics/environment_creation/) will assist you. We encourage and highly appreciate submissions via PRs to integrate these environments into `fancy_gym`.
+`fancy_gym` offers a large variety of reinforcement learning environments under the unifying interface
+of [OpenAI gym](https://gymlibrary.dev/). We provide support (under the OpenAI gym interface) for the benchmark suites
+[DeepMind Control](https://deepmind.com/research/publications/2020/dm-control-Software-and-Tasks-for-Continuous-Control)
+(DMC) and [Metaworld](https://meta-world.github.io/). If those are not sufficient and you want to create your own custom
+gym environments, use [this guide](https://www.gymlibrary.dev/content/environment_creation/). We highly appreciate it, if
+you would then submit a PR for this environment to become part of `fancy_gym`.  
+In comparison to existing libraries, we additionally support to control agents with movement primitives, such as Dynamic
+Movement Primitives (DMPs) and Probabilistic Movement Primitives (ProMP).
 
 ## Movement Primitive Environments (Episode-Based/Black-Box Environments)
 
-<p align="justify">
-Movement primitive (MP) environments differ from traditional step-based environments. They align more with concepts from stochastic search, black-box optimization, and methods commonly found in classical robotics and control. Instead of individual steps, MP environments operate on an episode basis, executing complete trajectories. These trajectories are produced by trajectory generators like Dynamic Movement Primitives (DMP), Probabilistic Movement Primitives (ProMP) or Probabilistic Dynamic Movement Primitives (ProDMP).
-</p>
-<p align="justify">
-Once generated, these trajectories are converted into step-by-step actions using a trajectory tracking controller. The specific controller chosen depends on the environment's requirements. Currently, we support position, velocity, and PD-Controllers tailored for position, velocity, and torque control. Additionally, we have a specialized controller designed for the MetaWorld control suite.
-</p>
-<p align="justify">
-While the overarching objective of MP environments remains the learning of an optimal policy, the actions here represent the parametrization of motion primitives to craft the right trajectory. Our framework further enhances this by accommodating a contextual setting. At the episode's onset, we present the context space—a subset of the observation space. This demands the prediction of a new action or MP parametrization for every unique context.
-</p>
+Unlike step-based environments, movement primitive (MP) environments are closer related to stochastic search, black-box
+optimization, and methods that are often used in traditional robotics and control. MP environments are typically
+episode-based and execute a full trajectory, which is generated by a trajectory generator, such as a Dynamic Movement
+Primitive (DMP) or a Probabilistic Movement Primitive (ProMP). The generated trajectory is translated into individual
+step-wise actions by a trajectory tracking controller. The exact choice of controller is, however, dependent on the type
+of environment. We currently support position, velocity, and PD-Controllers for position, velocity, and torque control,
+respectively as well as a special controller for the MetaWorld control suite.  
+The goal of all MP environments is still to learn an optimal policy. Yet, an action represents the parametrization of
+the motion primitives to generate a suitable trajectory. Additionally, in this framework we support all of this also for
+the contextual setting, i.e. we expose the context space - a subset of the observation space - in the beginning of the
+episode. This requires to predict a new action/MP parametrization for each context.
 
 ## Installation
 
 1. Clone the repository
 
-```bash
+```bash 
 git clone git@github.com:ALRhub/fancy_gym.git
 ```
 
 2. Go to the folder
 
-```bash
+```bash 
 cd fancy_gym
 ```
 
 3. Install with
 
-```bash
+```bash 
 pip install -e .
 ```
 
-We have a few optional dependencies. If you also want to install those use
+In case you want to use dm_control oder metaworld, you can install them by specifying extras
 
-```bash
-pip install -e '.[all]' # to install all optional dependencies
-pip install -e '.[dmc,metaworld,box2d,mujoco,mujoco-legacy,jax,testing]' # or choose only those you want
+```bash 
+pip install -e .[dmc,metaworld]
 ```
 
+> **Note:**   
+> While our library already fully supports the new mujoco bindings, metaworld still relies on
+> [mujoco_py](https://github.com/openai/mujoco-py), hence make sure to have mujoco 2.1 installed beforehand.
+
 ## How to use Fancy Gym
 
 We will only show the basics here and prepared [multiple examples](fancy_gym/examples/) for a more detailed look.
 
-### Step-Based Environments
-
-Regular step based environments added by Fancy Gym are added into the `fancy/` namespace.
-
-| :exclamation: Legacy versions of Fancy Gym used `fancy_gym.make(...)`. This is no longer supported and will raise an Exception on new versions. |
-| ----------------------------------------------------------------------------------------------------------------------------------------------- |
+### Step-wise Environments
 
 ```python
-import gymnasium as gym
 import fancy_gym
 
-env = gym.make('fancy/Reacher5d-v0')
-# or env = gym.make('metaworld/reach-v2') # fancy_gym allows access to all metaworld ML1 tasks via the metaworld/ NS
-# or env = gym.make('dm_control/ball_in_cup-catch-v0')
-# or env = gym.make('Reacher-v2')
-observation = env.reset(seed=1)
+env = fancy_gym.make('Reacher5d-v0', seed=1)
+obs = env.reset()
 
 for i in range(1000):
     action = env.action_space.sample()
-    observation, reward, terminated, truncated, info = env.step(action)
+    obs, reward, done, info = env.step(action)
     if i % 5 == 0:
         env.render()
 
-    if terminated or truncated:
-        observation, info = env.reset()
-```
+    if done:
+        obs = env.reset()
+``` 
+
+When using `dm_control` tasks we expect the `env_id` to be specified as `dmc:domain_name-task_name` or for manipulation
+tasks as `dmc:manipulation-environment_name`. For `metaworld` tasks, we require the structure `metaworld:env_id-v2`, our
+custom tasks and standard gym environments can be created without prefixes.
 
 ### Black-box Environments
 
-All environments provide by default the cumulative episode reward, this can however be changed if necessary. Optionally, each environment returns all collected information from each step as part of the infos. This information is, however, mainly meant for debugging as well as logging and not for training.

 If you created a new task wrapper, feel free to open a PR, so we can integrate it for others to use as well. Without the
 integration the task can still be used. A rough outline can be shown here, for more details we recommend having a look
 at the [examples](fancy_gym/examples/).
 
-If the step-based is already registered with gym, you can simply do the following:
-
 ```python
-fancy_gym.upgrade(
-    id='custom/cool_new_env-v0',
-    mp_wrapper=my_custom_MPWrapper
-)
-```
+import fancy_gym
 
-If the step-based is not yet registered with gym we can add both the step-based and MP-versions via
+# Base environment name, according to structure of above example
+base_env_id = "dmc:ball_in_cup-catch"
 
-```python
-fancy_gym.register(
-    id='custom/cool_new_env-v0',
-    entry_point=my_custom_env,
-    mp_wrapper=my_custom_MPWrapper
-)
-```
-
-From this point on, you can access MP-version of your environments via
-
-```python
-env = gym.make('custom_ProDMP/cool_new_env-v0')
+# Replace this wrapper with the custom wrapper for your environment by inheriting from the RawInferfaceWrapper.
+# You can also add other gym.Wrappers in case they are needed, 
+# e.g. gym.wrappers.FlattenObservation for dict observations
+wrappers = [fancy_gym.dmc.suite.ball_in_cup.MPWrapper]
+kwargs = {...}
+env = fancy_gym.make_bb(base_env_id, wrappers=wrappers, seed=0, **kwargs)
 
 rewards = 0
-observation, info = env.reset()
+obs = env.reset()
 
 # number of samples/full trajectories (multiple environment steps)
 for i in range(5):
     ac = env.action_space.sample()

-## MP-Based Envs
-
-All envs also exist in MP-variants. Refer to them using `metaworld_ProMP/<name-v2>` or `metaworld_ProDMP/<name-v2>` (DMP is currently not supported as of now).
+These are the Environment Wrappers for selected [Metaworld](https://meta-world.github.io/) environments in order to use our Movement Primitive gym interface with them. 
+All Metaworld environments have a 39 dimensional observation space with the same structure. The tasks differ only in the objective and the initial observations that are randomized. 
+Unused observations are zeroed out. E.g. for `Button-Press-v2` the observation mask looks the following:
+```python
+    return np.hstack([
+        # Current observation
+        [False] * 3,  # end-effector position
+        [False] * 1,  # normalized gripper open distance
+        [True] * 3,  # main object position
+        [False] * 4,  # main object quaternion
+        [False] * 3,  # secondary object position
+        [False] * 4,  # secondary object quaternion
+        # Previous observation
+        [False] * 3,  # previous end-effector position
+        [False] * 1,  # previous normalized gripper open distance
+        [False] * 3,  # previous main object position
+        [False] * 4,  # previous main object quaternion
+        [False] * 3,  # previous second object position
+        [False] * 4,  # previous second object quaternion
+        # Goal
+        [True] * 3,  # goal position
+    ])
+```
+For other tasks only the boolean values have to be adjusted accordingly.
