-# What is Synthetic Data?
+# YData Synthetic
+A package to generate synthetic tabular and time-series data leveraging the state of the art generative models.
+## Synthetic data
+### What is synthetic data?
 Synthetic data is artificially generated data that is not collected from real world events. It replicates the statistical components of real data without containing any identifiable information, ensuring individuals' privacy.
 
-# Why Synthetic Data?
+### Why Synthetic Data?
 Synthetic data can be used for many applications:
-- Privacy
-- Remove bias
-- Balance datasets
-- Augment datasets

 # ydata-synthetic
 This repository contains material related with Generative Adversarial Networks for synthetic data generation, in particular regular tabular data and time-series.
 It consists a set of different GANs architectures developed using Tensorflow 2.0. Several example Jupyter Notebooks and Python scripts are included, to show how to use the different architectures.
