crumb is a cli tool adding and managing crumbs your in your WD. So what is crumbs you might ask? Its whatever you want it to be.
A crumb inside a crumb file follows has the following syntax.. no more no less

[Markers.todo]
Prefix='"[ ] "'
[Markers.done]
Prefix='"[x] "'
[Markers.selected]
Prefix='" > "'
[Markers.backlog]
