 ## Get started
 
-Generate your project with cookiecutter:
+If you already know [cookiecutter](https://github.com/cookiecutter/cookiecutter), just generate your project with:
 
 ```bash
 cookiecutter https://github.com/grok-ai/nn-template
 ```
 
-> This is a *parametrized* template that uses [cookiecutter](https://github.com/cookiecutter/cookiecutter).
-> Install cookiecutter with:
->
-> ```pip install cookiecutter```

+## Strengths  
+- **Actually works for [research](https://grok-ai.github.io/nn-template/papers/)**!
+- Guided setup to customize project bootstrapping;
+- Fast prototyping of new ideas, no need to build a new code base from scratch;
+- Less boilerplate with no impact on the learning curve (as long as you know the integrated tools);
+- Automatize via GitHub actions: testing, stylish documentation deploy, PyPi upload;
+- Enforce Python [best practices](https://grok-ai.github.io/nn-template/features/bestpractices/);
 
 ## Integrations

+# MetaData
+
+The *bridge* between the Lightning DataModule and the Lightning Module.
+
+It is responsible for collecting data information to be fed to the module.
+The Lightning Module will receive an instance of MetaData when instantiated,
+both in the train loop or when restored from a checkpoint.
+
+!!! warning
+
+    MetaData exposes `save` and `load`. Those are two user-defined methods that specify how to serialize and de-serialize the information contained in its attributes.
+    This is needed for the checkpointing restore to work properly and **must be
+    always implemented**, where the metadata is needed.
+
+This decoupling allows the architecture to be parametric (e.g. in the number of classes) and
+DataModule/Trainer independent (useful in prediction scenarios).
+Examples are the class names in a classification task or the vocabulary in NLP tasks.
