This section goes over some of the internals of Yorkie, such as the CRDT, ordering of messages via Lamport clocks, etc.

Note: Because this section explains internals for understanding the techniques, It is not essential for using Yorkie.


For more details on the techniques used for understanding Yorkie, we recommend reading the following papers.
