Check out the contur code from our repository at gitlab and checkout the tag you want to use.
We always recommend the latest release tag, or even the associated branch if you want the very latest bug fixes.
The README in the project overview provides some instructions on how to run a Herwig/rivet/contur run on a single parameter parameter
point, and also on how to run a simple parameter scan on an example model.
We also have a docker-based tutorial produced for
various schools (YETI and MCnet) which is available here.
To get some information about the available options, see
(the tutorial needs updating for the release version)
