+  In-repo composite action to setup Conda and install parcels. Installation of parcels relies on
+  `setup.py` file being available in the root. For general setup of Anaconda environments, just use
+  the `mamba-org/setup-micromamba@v1` action (setting C variables as required), or the `conda-incubator/setup-miniconda` action.
