# greenvironment-server
Server of the greenvironment social network.
## Install
You need to install a nodejs runtime to run the greenvironment server.
Then you need to install all requirements. To do so, open a terminal in the
greenvironment project folder and execute "npm i". You can build the project by
executing "gulp" in the terminal. To run the server you need
to execute "node ./dist".
