getting_started.md not up to date

[RemyDelion]

Hello Tom,
First, thank you for giving us acces to you platform and all its AMIs!
I know you are overwhelmed by your job, but I have a few notes concerning the documentation.

In the medium documentation (step1, step2, ...) the command lines to deploy the CyberRange do not use terraform commands directly, but make commands. This is not the same in getting_started.md, so it is confusing.

The Makefile is very simple to understand, once we have understood to add environment variables ENV and REGION, like:

make init ENV=demo REGION=eu-west-2
make plan ENV=demo REGION=eu-west-2
make cyberRange ENV=demo REGION=eu-west-2
...
make destroy-force ENV=demo REGION=eu-west-2

Furthermore, the make cyberRange command needs to have previously installed inspec, because of checkLab sub-command call.

At the begining, the ENV variable rule was not clear to me, but it is only an arbitrary name for the deployed platform.

Please Tom, could you upgrade the getting_started.md file, or simplify it by giving links to medium documentation?
Thanks in advance,
Regards, Remy
