Understanding process for CZML from STK and CesiumJS

I’m not a coder, but I use STK all the time and would like to visualize my scenarios in CesiumJS. Thats the primary reason Cesium was created right?

I don’t want to use the online version of CesiumJS so I downloaded it. I have used the CZML Plugin in STK to create my CZML files but when I drag them into Cesium nothing works and I get JSON errors. Does anyone have a straight forward procedure I could follow to launch CesiumJS and import my STK CZML scenarios into it? Right now I’m using Node.js at Localhost:3000 for my server.
