README.md

Quantum Leaps, LLC is a professional open source company that brings the asynchronous, event-driven, and non-blocking Active Objects (Actor model) to real-time embedded programming. Quantum Leaps' QP Real-Time Event Frameworks (RTEFs) and the tools around them enable embedded developers to efficiently apply the Active Object (Actor) model, hierarchical state machines, graphical modeling, and automatic code generation.

Issue Tacking and Support
