software requeirements: node.js and npm

To implement on server: first, environment variables would need to be set.
A .env.example file is supplied. The values will be supplied privately. 

To start the webpage: first, clone the repo.
second, change your current working directory to the root of the repo.
third, run npm install.
finally, run npm start. 

Alternatively, perhaps ideally, a process manager which can restart the node server on server reboot or crash would be implemented to run the server. 

pm2 is a popular process manager for node.js applications.

To install pm2, run `npm install pm2 -g`.

To start the server with pm2, run `pm2 start server.js`.

To make the application run on server reboot, run `pm2 startup` and follow the instructions.

This will start the server on port specified in environment || 8080 by default.
