+or tag changed over time to reference different commits, particularly for information not surfaced through {{.EmphasisLeft}}dolt log{{.EmphasisRight}}.
+The data from Dolt's reflog comes from [Dolt's journaling chunk store](https://www.dolthub.com/blog/2023-03-08-dolt-chunk-journal/). 
+This data is local to a Dolt database and never included when pushing, pulling, or cloning a Dolt database. This means when you clone a Dolt database, it will not have any reflog data until you perform operations that change what commit branches or tags reference.
+
+Dolt's reflog is similar to [Git's reflog](https://git-scm.com/docs/git-reflog), but there are a few differences:
+- The Dolt reflog currently only supports named references, such as branches and tags, and not any of Git's special refs (e.g. {{.EmphasisLeft}}HEAD{{.EmphasisRight}}, {{.EmphasisLeft}}FETCH-HEAD{{.EmphasisRight}}, {{.EmphasisLeft}}MERGE-HEAD{{.EmphasisRight}}).
+- The Dolt reflog can be queried for the log of references, even after a reference has been deleted. In Git, once a branch or tag is deleted, the reflog for that ref is also deleted and to find the last commit a branch or tag pointed to you have to use Git's special {{.EmphasisLeft}}HEAD{{.EmphasisRight}} reflog to find the commit, which can sometimes be challenging. Dolt makes this much easier by allowing you to see the history for a deleted ref so you can easily see the last commit a branch or tag pointed to before it was deleted.`,
