+# About QP/C++ Real-Time Event Framework
+QP/C++ real-time event framework (RTEF) is a lightweight implementation of
+the asynchronous, event-driven [Active Object (a.k.a. Actor) model of computation][AOmod]
+specifically designed for real-time embedded systems, such as microcontrollers (MCUs).
 QP/C++ is both a software infrastructure for building applications consisting
 of Active Objects (Actors) and a runtime environment for executing the Active
 Objects in a deterministic, real-time fashion. Additionally, QP/C++ Framework

+The **SafeQP/C** and **SafeQP/C++** frameworks were originally derived from QP/C and QP/C++,
+respectively, but were extensively reengineered for the safety market using compliant
+Software Safety Lifecycle (SSL). In this process, the QP framework functional model has been
+subjected to a full Hazard and Risk Analysis, which identified all areas of weakness within
+the functional model and API. These findings led to creation of Safety Requirements and risk
+mitigation by Safety Functions, which were subsequently implemented, verified, and validated.
+The SafeQP frameworks are accompanied by the "SafeQP Certification Kits", which provide
+developers with ready-to-use artifacts, enabling them to save time, mitigate risk, and reduce
+costs during application certification for safety-critical devices in the industrial, medical,
+aerospace, and automotive industries. Please [contact Quantum Leaps](#contact-information)
+for more information about the SafeQP frameworks and the "Certification Kits".

+> **NOTE:** The SafeQP/C++ edition remain fully API- and functionally compatible with the
+corresponding standard QP/C++ framework. This ensures existing QP/C Applications can transition
+seamlessly to SafeQP/C++ without requiring any modifications. SafeQP/C edition retain QP/C++
+Frameworks' hallmark features, including a small memory footprint, excellent efficiency,
+and hard real-time functionality.
