Edge Fields
The starting point of Breadcrumbs is fields, which let you add types to your links. For example, the [[Father]] note could have a child field pointing to [[Me]], and [[Me]] could have a parent field pointing to [[Mother]]:
Father.md
---child: "[[Me]]"---Me.md
---parent: "[[Mother]]"---
%% Works with Dataview inline fields, too %%
parent:: [[Mother]]This would result in the following graph:
flowchart LR 1(Father) -- child --> 2(Me) 2 -- parent --> 3(Mother)
By default, there will be 5 starting fields: up, same, down, next, and prev, representing 5 different directions. These can take you quite far, and you may be happy using just these fields, but you can customise them further. To get started, you need to tell Breadcrumbs which other fields you intend to use to “type” your links. This can be done under Settings > Edge Fields:

For example, you can model personal relationships using fields like parent, child, and sibling. Or you can create a layered system of daily notes using fields like day, month, and year.
