* **Note:** Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.



### Install MongoDB
At this time of writing, Homebrew has MongoDB version **3.2.10** as default formulae in its main repository :

* Enter the following command : `$ brew info mongodb`  
* Expected output: **mongodb: stable 3.2.10 (bottled)**

To install MongoDB enter : `$ brew install mongodb` 


## Additional configuration
