Welcome! This is my attempt at creating an SS13 remake using node.js.
Install node.js and NPM (npm should automatically be installed when you install node.js) and run npm install in the root directory of the repo and client_src. Also, run npm install -g gulp-cli. To build the client, run gulp build in the client_src directory.
Run node index.js in the root directory of the repository. To join the server connect to localhost:8080 using a web browser.
