+### ALPI Tasking Interface
+
+The Task-Aware SYCL library relies on the [ALPI](https://gitlab.bsc.es/alpi/alpi) interface to communicate with
+the underlying tasking runtime system. This interface is internally used by TASYCL to spawn internal tasks, to
+block user tasks, or add external events to them.
+
+The required interface is ALPI 1.0 (or any compatible) and it is included in the [ALPI.hpp](src/common/ALPI.hpp)
+header. Any tasking runtime system can support this TASYCL library by providing support to this interface version.
