Installation instructions use git clone --tag

Hi MITRE CALDERA team,

I found what appears to be a mistake in the installation instructions.

In the README, the “Full steps” section currently says:

git clone https://github.com/mitre/caldera.git --recursive --tag x.x.x

but this didn't work for me.

I believe the intended command could be:

git clone https://github.com/mitre/caldera.git --recursive --branch x.x.x

Could it be a mistake in the instructions?

Thanks.
