# multi-line comment
<<:
  NOTE:
        be sure to run --> npm install express body-parser mongodb@2.2.33 <-- when intializing a package for programming assignment 3

        Afterwards, go to /data/db run mongodb to start the mongodb server.
        in a separate tab run mongo to have the mongodb client connect to the server.
        be sure to create the database (use <dbName>) and collection (db.<dbName>.createCollection('<collName>')).
        so that when you referenc it in your NodeJS entry point file the code will work.

        from the client you can run db.<dbName>.find() to see if the data was stored correctly
