Welcome to the ICON Model documentation

It’s the job that’s never started as takes longest to finish - J.R.R. Tolkien

The website docs.icon-model.org contains a collection of ICON documentation including references to documentation available at other places. We do not claim that this documentation is complete, but we hope you will still find it helpful.

Release Cycle & Plans

You can find the latest release here: ICON Release
It is planned to publish at least two major ICON open source releases per year, most probably in spring and autumn. For special purposes a new version can also be published in between, e.g. to provide a release with new features for special events like a summer school or a model training.
