You can read an introduction to the ideas behind Kangaroo here:

Kangaroo2 is now available for testing (see full announcement here). Please bear in mind this is still a work-in-progress, and features are still subject to change.

You can download it from here:

This thread contains some troubleshooting tips if you have problems getting it installed and working:

The main source of example files for the latest version is here:

Some further example files for version 2.0 can be found here:

with more to follow - if there is some particular feature you would like more examples of information on please ask there.

The Kangaroo2 solver library is now separate from the Grasshopper components, and can also be referenced and used in scripts, either in the GH VB/C#/Python components, or in RhinoScript/PythonScript in Rhino. Questions about these can also be posted on:

Kangaroo2 is a complete rewrite, and the main solver/goal/force components are not cross-compatible with the previous version. However, you can keep both versions installed together allowing older definitions to be opened, and for now this is recommended, as there are also several utility and mesh processing functions relevant to both versions.

While v2 introduces many new features and improvements, not all the features from the old version currently have equivalents in the new version, but the plan is to add them all over time.

The links below are for the old version. More documentation and videos for the new version to appear soon.
