Setting up Sliding Sync

Introduction to Sliding Sync

Sliding Sync is a backend component required by the Element X client beta. It provides a mechanism for the fast synchronisation of Matrix rooms. It is not recommended for production use and is only provide to enable the usage of the Element X client. The current version does not support SSO (OIDC/SAML/CAS).
