Prefect has two editions — open source and Prefect cloud.
To get going with Prefect open source, one can install Prefect from pip installer.
It may be advised to create a separate conda environment or virtual environment.
To use virtual environment,
virtualenv {{name-of-the-virtual-environment}}
To activate the virtual environment
source {{name-of-the-virtual-environment}}/bin/activate
One may choose to install prefect within that virtual environment,
pip install -U prefect
To start the prefect server and access the UI,

Open a browser and enter,
