# Data Sync/Save System

For serialising data to saves and synchronising with clients, a custom data sync system based on Java Annotations is used.

- See [Usage](Usage.md) for a guide on using the system
- See [Annotations](Annotations.md) for a list of annotations provided by the system
- See [Migrating From LDLib SyncData](Migrating-From-LDLib-SyncData.md) for instructions on how to migrate from the LDLib SyncData system, which was used in versions 7.x and lower.
