The test section of the readme needs to reference a needed pre-req and also needs a more accurate bats installation guide.

The bats test framework relies on the JQ parser but there is no mention of it's installation. It can easily be installed (MacOS) with brew install jq (https://formulae.brew.sh/formula/jq)

Bats installation is documented as "brew install bats-core bats-support bats-assert", but as such only bats-core is installed. Using "brew install bats-core", followed by "brew tap bats-core/bats-core", "brew install bats-support", and "brew install bats-assert", allowed the tests to load the relied upon support and assert libs.
