# Create immutable versions

Snapshot a design so it can be reviewed, approved, and exported.

**Who this is for:** Editors preparing work for review.

A **version** is an immutable snapshot of a template’s document at a point in time, identified by a server-computed content hash. Versions are what you review, approve, and export - drafts keep changing, versions do not.

- Create a version from the current draft when it’s ready for review.
- Versions are append-only; they are never edited in place.
- Restore a past version as a new draft to branch from it (Memo also captures a recovery snapshot).

## Expected result

You have an immutable version ready to submit for review.
