+Milestone 1: 
+Building the docker image: 
+docker build --tag=humid .
+
+Run build:
+docker run -p 8080:8080 --privileged humid
+
+Be aware: 
+We instantiate a socket in the public/readings.js file. 
+In order for the socket to work, you give the ip as parameter to the io.connect method. 
+You get the IP by using:
+hostname -I
+Then you are able to access the data through the browser on localhost:8080
+
+Also be aware: 
+The buttons do nothing yet ¯\_(?)_/¯
