A Card's history will show you exactly what edits were made and allows you to compare the current version of the Card to previous versions. For Authors, this can make the verification process clearer and more thorough because you will be able to reference all iterations of the Card.

2. Click the Details tab at the top of the Card
3. Scroll down to Revision History:
4. If you would like to compare the current Card to its most recent form, you can click Compare to: Current Version.
5. If you'd rather see all the edits made between two old Versions, select Compare to: Revision #
When viewing all changes to a Card, insertions are shown in green, while deletions are shown in red.
