It's not published yet, so you'll have to clone the repo:
git clone https://github.com/FCO/Red.git
install it's dependencies
zef install . --deps-only
once cloned, you can run it with -Ilib on the repo's root
perl6 -Ilib examples/blog/index.p6
perl6 -Ilib -MRed -e 'your code here'
perl6 -Ilib t/02-tdd.t # this runs 1 test file
or you can run the tests with
zef test .
or install it with
zef install .
