+In this project we will explore the NumPy (Numerical Python) Python library, which is
+used in almost every field of science and engineering. It’s practically the standard for working with numerical data in Python. It is an introduction to get a better understanding of how to work with this library.</br>
+Main points, including:</br>
+* how to work with arrays</br>
+* how to create nd.arrays</br>
+* creating arrays with standard functions such as arange(), random(), or linespace()</br>
+* What exactly is broadcasting and how does it work</br>
+* How to do linear algebra with NumPy</br>
+* Image manipulation with a NumPy array </br>
