All the docs that parrot ships with are available at this site. You can generate a local copy by running make html in the build directory.
We also provide old documentation for all previously released parrot versions at our github page.
Parrot Babysteps is called a nice tutorial to learn the basics of the PIR syntax. It is a raw Parrot beginner's introduction outside the official documentation.
