 This repositorycollects Python scripts and Jupyter notebooks that allow the user to test different variational algorithms. It contains our custom functions (e.g. VHA ansatz, PBO Hamiltonian)
 that are built upon Qiskit libraries.
 
+The repository is organized as follows:
+- 'misc' folder contain the notebooks and scripts that showcase the variational algorithms
+- 'qiskit_mod' contains our custom functions that are built upon Qiskit libraries as well as the QLM custom junction and helpers:
+    - 'qiskit_nat' the customize function built upon qiskit_nature
+    - 'qiskit_ter' the customize function built upon qiskit_terra
+    - 'my_junction.py' the QLM custom junction used to run the variational algorithms with QLM backends
+    - 'uploader_junction.py' helper to upload the junction to QLMaaS server, so that it can be found in the remote library
+    - 'wrapper2myqlm.py' helper to wrap the variational algorithms using QLM stack
+- 'tests' unit tests for the variational algorithms
