				+Для работы чата:
			
 
				+
			
 
				+- `git clone http://gitlab.a-level.com.ua/gitgod/socketchat`
			
 
				+- установите [nodejs 8+](https://nodejs.org/uk/)
			
 
				+- зайдите в папку с проектом (`cd`)
			
 
				+- `npm install` для установки всех нужных библиотек. Они **уже** прописаны в файле `package.json` и `package-lock.json`. `npm` прочитает эти файлы и установит все как надо.
			
 
				+- `node index.js` для запуска сервера
			
 
				+- [дом родной, a/я 4000](http://localhost:4000) для захода на сервер (загрузки `index.html`)
