 ## Usage
 
+### TRPL
+
 TRPL can be used just like SB3's PPO:
 
-```
+```python
 import gymnasium as gym
 from metastable_baselines2 import TRPL
 
+env_id = 'LunarLanderContinuous-v2'
 projection = 'Wasserstein' # or Frobenius or KL
 
-model = TRPL("MlpPolicy", env_id, n_steps=128, seed=0, policy_kwargs=dict(net_arch=[16]), projection_class=projection, projection_kwargs={'mean_bound': mean_bound, 'cov_bound': cov_bound}, verbose=1)
+model = TRPL("MlpPolicy", env_id, n_steps=128, seed=0, policy_kwargs=dict(net_arch=[16]), projection_class=projection, verbose=1)
 
 model.learn(total_timesteps=100)
 ```
 
+Configure TRPL py passing `projection_kwargs` to TRPL:
+
+```python
+model = TRPL("MlpPolicy", env_id, n_steps=128, seed=0, policy_kwargs=dict(net_arch=[16]), projection_class=projection, projection_kwargs={'mean_bound': mean_bound, 'cov_bound': cov_bound}, verbose=1)
+```
+
 For avaible projection_kwargs have a look at [Metastable Projections](https://git.dominik-roth.eu/dodox/metastable-projections).
 
+### Full Covariance
+
+SB3 does not support full covariances (only diagonal). We still provide support for full covariances via the seperate PCA package. (But since we don't actually want to use PCA ('Prior Conditioned Annealing'), we pass 'skip_conditioning=True'; this will lead to the underlying Noise being used directly.)
+
+We therefore pass `use_pca=True` and `policy_kwargs.dist_kwargs = {'Base_Noise': 'WHITE', par_strength: 'FULL', skip_conditioning=True}`
+
+```python
+# We support PPO and TRPL, (SAC is untested, we are open to PRs fixing issues)
+model = TRPL("MlpPolicy", env_id, n_steps=128, seed=0, policy_kwargs=dict(net_arch=[16], ), projection_class=projection, verbose=1)
+
+model.learn(total_timesteps=100)
+```
+
+The supportted values for `par_strength` are:
+
+​    SCALAR: We only learn a single scalar value, that is used along the whole diagonal. No covariance is modeled.
+
+​    DIAG: We learn a diagonal covariance matrix. (e.g. only variances).
+
+​    FULL: We learn a full covariance matrix, induced via cholesky decomp.
+
+​    CONT_SCALAR: Same as SCALAR, but the scalar is not global, it is parameterized by the policy net.
+
+​    CONT_DIAG: Same as DIAG, but the values are not global, they are parameterized by the policy net.
+
+​    CONT_HYBRID: We learn a parameric diagonal, that is scaled by the policy net.
+
+​    CONT_FULL: Same as FULL, but parameterized by the policy net.
