How to Save Versions
===

HackMD periodically saves a version every 10 minutes when you're editing, so you don't have to worry about saving and can easily revert the note back to its previous state.

## Save Versions
You can also save your notes manually and name it - see how:

All previous unnamed, auto-saved versions will fold under your newly-named version.

## Compare Versions
You can compare any two versions, named or un-named. Additions from the one being compared will be marked in green while text removals in red. There's also option to filter only named versions.


## Edit and Delete Versions
Name and description can be changed, but the revisions (editing history) will stay.
