Getting started

No tooling needed, you don't even have to install anything. To get started first play with our demos to get a feel what power Reken provides, and more importantly, how you can unleash it. Once you get a feel for that, try out Reken for yourself in our REPL environment. If you need help with the functionality scan through our documentation to get an overview of the various features. When ready to start with a new or existing HTML document, add the link to our hosted library file (5kb) and sprinkle in some Reken goodness.
