Local deploy

Hi, i’m a cs teacher from china and works in a meddle school. I found codingame is so cool to teach programing, but it’s too slow and difficulty to access codingame.com in my country. In this fact, i want to know how to local deply this project in my school? I found some code in github but there is no step by step manual to build it. Any body can help me and pls ignore my pool english:)
