MongoDB installation

First, you need to install MongoDB into your local machine. It is distributed as a standalone server as well as a cloud service. Download the latest version from: https://www.mongodb.com/download-center/community. Choose the appropriate OS from the list and install it on your machine. 

MongoDB doesn't has any UI to access it. However, it provides another tool called Compass and can be downloaded from: https://www.mongodb.com/download-center/compass. Choose the appropriate version and target platform and download them. In most cases, it is directly executable. By default, MongoDB is accessible with the 27017 port. Just connect Compass to the MongoDB server to make sure it is running before connecting.
