    ## Data

    This section is broken down into 4 sections that match the Crud Verbs of Create, Read, Update, Delete. Each table lists the commands most commonly used when working with data inside collections as it pertains to its verb.
    This section is broken down into 5 sub-sections. The first 4 match the CRUD Verbs of Create, Read, Update, Delete, and the last one is a list of Combos like `findAndUpdate`.

    ### Create

    Create One | `db.<collection>.insertOne(<document>)` | Inserts a document into the collection. IE: db.cars.insertOne({make:"ford"}). [Doc](https://docs.mongodb.com/manual/reference/method/db.collection.insertOne/#db.collection.insertOne)
    Create One/Many | `db.<collection>.insert([{},{}...)` | Inserts One or more documents into the collection. If an array is passed in it will make a record of each document in the array. Otherwise it will accept a single document. [Doc](https://docs.mongodb.com/manual/reference/method/db.collection.insert/#db.collection.insert)
