 # Websockets
 
 ## Introduction
+### Why are we going to use websockets? 
+With websockets you can establish a connection between the client and the server, and both can send data fast to each other. This is useful for real-time applications like for our project to plot live graphs of the data we are collecting from the sensors.
+
+### How to use websockets
+There are different languages to serve websockets with, but we are going to use Python with the library `websockets`. This library is easy to use and has a lot of documentation.
