# 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".
