+                       INTEGRATION AS LIBRARIES
+                       ========================
+
+While this package contains the necessary applications to execute the IVAS encoder,
+decoder, renderer and ISAR post renderer, it is envisioned that the libraries used
+would be integrated into custom applications.
+
+It should be noted that this library is not thread-safe by default. Thus, when using
+the IVAS libraries in a multi-threaded environment, proper synchronization of API
+calls is required to prevent race conditions by concurrent access to IVAS internal
+state memory, FIFO queues buffers or any other data structures. Potential mechanisms
+include e.g. mutexes, spinlocks and semaphores. The API calls are at the present not
+optimized for fine-granular locking of just critical sections. Some sensitive
+sections have thus been marked with a comment in the form /* LOCK XYZ BEGIN */ and
+/* LOCK XYZ END */ to provide guidance where code could be modified to prevent
+some potential race conditions.
