 - GCC
 - Make
 - CMake
+- aidge_core
 - Python (optional, if you have no intend to use this library in python with pybind)
 
+## Pip installation
 
-## Compilation
+You will need to install first the aidge_core library before installing aidge_cpu.
+Also, make sure that the install path was set before installing aidge_core library.
+Then run in your python environnement : 
+``` bash
+pip install . -v
+```
+
+## Standard C++ Compilation
 
 You will need to compile first the Core library before compiling the CPU one.
 The makefile is designed to do it for you.
