To get the latest released version and install it into a conda environment:
conda install -c asteroid-institute precovery

To install the bleeding edge source code, clone this repository and then:

If you use conda to manage packages and environments:
conda install -c defaults -c conda-forge --file requirements.txt
pip install . --no-deps

If you would rather download dependencies with pip:
pip install -r requirements-pip.txt
pip install . --no-deps

Note that, openorb is not available on the Python Package Index and so it would still need to be installed either via source install or via conda.
