+Summary
+-------
+cryoSBI is a Python module for simulation-based inference in cryo-electron microscopy. The module provides tools for simulating cryo-EM particles, training an amortized posterior model, and sampling from the posterior distribution.
+The code is based on the SBI libary `Lampe <https://lampe.readthedocs.io/en/stable/>`_, which is a using Pytorch.
