--  Make sure your current working directory is clean by checking the output
-   of ``git status`` and by running ``git clean -xdf`` to remove any files

--  Edit ``package/meta.yaml`` and uncomment the lines starting with ``git_rev`` and
-   ``git_url``, remove the line starting with ``path`` in the ``source``
-   section.
--  Activate the base environment ``conda activate base``
--  Install the required packages:
-   ``conda install -y conda-build conda-verify ripgrep anaconda-client``
--  Run ``conda build package -c conda-forge`` to build the

--  If the build was successful, upload the package to the esmvalgroup
