How do I update an existing installation of FMPy?

If you've installed FMPy with conda, open a conda prompt and run

conda update -c conda-forge fmpy

If you've installed FMPy with pip, run

pip install fmpy --upgrade

How do I install a development build?

go to the CI server
select Pipelines > Pipelines
on the Runs page select the commit you want
on the Summary tab click N published under Related (where N is the number of artifacts)
hover over your platform (e.g. windows-python-3.6), click on ... and select Download artifacts
extract the ZIP archive
open a command line and change into directory where you extracted the archive
on the command line run python -m pip install <path-to-wheel> (where <path-to-wheel> is the path of the FMPy Wheel (*.whl))
