README.rst file is not clearly written

Hi there!

I am facing a bit trouble due to the Readme.rst file. The file has " …code-block::sh " in some line. What does the " … " mean and where exactly do we have to run this command? Also what to do after downloading the MongoDB tools? How to install them is not specified there while I think it should have atleast the link to how to install.

P.S: I know the course itself has a clearer view to the file, but this can create confusion among students and is advisable to update as per required.

Thank You
