> ## Using Mongo
>
> Run an instance of MongoDB with `mongod` in a terminal, open up another tap and open a mongo client that connects to the previous instance of Mongo, with `mongo`. Use a databse called demo, `use demo`, and `show collections` to show what documents are stored, it should be empty since it is a new database. To Insert new data to a collection called names, use `db.names.insert({name: "IoT Champion"})`, show what collections we have now `show collections` and the new collection should come up, then find all data in our collection `db.names.find()` and insert new data `db.names.insert({name: "IoT Champion"}, power: "Over 9000")`.
