 ### Versions
 
-Datasets are [versioned](/langsmith/version-datasets) such that every time you add, update, or delete examples in your dataset, a new version of the dataset is created. This makes it easy to inspect and revert changes to your dataset in case you make a mistake. You can also [tag versions](/langsmith/version-datasets#tag-a-version) of your dataset to give them a more human-readable name. This can be useful for marking important milestones in your dataset's history.
