 Boosting variational eigenstate preparation algorithms limited by training and not device coherence by diagonalization double-bracket iteration.
 
-## Setup
+## Installation instructions
 
-Given you have `poetry` installed
+The package can be installed by source after cloning the repository:
 
 ```sh
-poetry install && poetry shell
+pip install -e .
 ```
 
 will install `boostvqe 0.0.1` and activate a dedicated working shell.
