After the CDR was released in 2018, the CEPC is moving towards its technical design steadily. A new software framework is under developing and various new detector concepts were proposed, which need validation, intensive and sophisticated simulation study, and optimization. The new CEPCSW is designed to meet all these requirements. This workshop is going to focus on the new CEPCSW. The new software is based on a more generic framework and modern event data model and within very broad international collaboration, which could provide all aspects support for the CEPC to perform R&D and physics study. This workshop is going to introduce the new software to new comers and help them get involve the detector and physics study more smoothly, which is going to cover detector geometry and material implementation, simulation, reconstruction, and a little bit analysis.
