 # MongoLearnPod
 An education GitPod module intended to teach individuals how to use mongo on any machine.
+
+
+
+
+## Unit Learning Objective
+Students should be to:
+1. Use Docker Compose to start and stop mongoDB environment
+2. Use Docker, Terminal & MongoExpress to teach basic mongoDB concepts
+3. Distinguish between the name of a docker image (mongo) and the container name (learn-mongo)
+4. Use NPM Scripts to store docker commands
+
+
+# What did you build
+Today we'll be learning how to use Docker Compose to learn MongoDB.
+
+## Unit Learning Objective
+Students should be to:
+1. Use Docker Compose to start and stop mongoDB environment
+2. Use docker exec to access the mongoDB Shell 
+3. Distinguish between the name of a docker image (mongo) and the container name (learn-mongo)
+4. Use NPM Scripts to store docker commands such as docker exec for mongo shell

+
+## About
+This is a brief mongo tutorial in GitPod and originally built for docker and docker compose which you can see [here](https://github.com/HansUXdev/OSS-Books/tree/master/JavaScript-First/00-JavaScript-DataBases/mongo).
+
+## Using Mongo Shell to build a database
+  Lets go ahead and create a new *collection* and use it. 
+
+  Type the following into the terminal: `use learnMongo`. 
+
+  We can then show the database we are using by using the `db` command.
+
+  Next we are going to insert some data into our new database.
+  To do this we'll use the the [insert](https://docs.mongodb.com/manual/tutorial/insert-documents/) command.
+
+
+  ```js
+  db.info.insert(
+    {
+      "country": "United States of America", 
+      "state": "Arizona", 
+      "cities": ["Phoenix", "Mesa", "Chandler"]
+    }
+  )
+  ```
+  This will insert a new *document* into the info *collection*.
+
+  **Exercise**
+  Next, you should come up with 2 other states, with atleast two cities in each.
+
+  Finally, we will use the [.find()]() method to find the document with a state of Arizona.
+
+  ```js
+  db.info.find({state:'Arizona'}).pretty()
+  ```
+  Note that the [.pretty()]() command just formates the data more properly.
+
+
+  By the end of the exercise your terminal should look something like following but with different examples:

+
+  If we open mongo-express, we should see a new database appeared. We can also use the terminal command `show dbs` to display them in terminal.

+
+## Using NPM Scripts
+  # Package.json is used to demostrate NPM Scripts for use with docker
+  Students should be able to:
+  * Identify the package.json file and the script section
+  * Modify the package.json file to add the docker command
+  ```
+  "mongo": "docker exec -it learn-mongo mongo",
+  ```
+  * Distinguish between the name of the docker image (mongo) and the container name (learn-mongo)
+
+  * Demonstrate Mongo Terminal Commands
+  1. Running with docker compose
+      - ```docker exec -it learn-mongo mongo```
