The classical-quantum combiner (CQC) interface is an interface between higher layers and hardware in a Quantum Internet. It comes with a Python, C and Rust library for constructing CQC messages. The Python library is definitely the best place to get started.
Documentation of CQC can be found at https://softwarequtech.github.io/CQC-Python/
The CQC can be used to either program hardware which supports the interface or the simulator https://github.com/SoftwareQuTech/SimulaQron.
More information about CQC can also be found in the paper on SimulaQron at https://arxiv.org/abs/1712.08032
