Provides the Python API/SPI for the Serverless Workflow Specification
This is a WIP implementation
With the SDK you can:
- WIP Programmatically build workflow definitions
- Parse workflow JSON and YAML definitions
- Validate workflow definitions
Python 3 required
pipenv required
pip install pipenv
pipenv install
pipenv shell
