# Folgezettel Heterarchy

Neuron allows you to organically build a Heterarchy out of your Zettelkasten over time. When a zettel links (see Linking) to another, it “branches off”1 to that zettel … using [[[...]]] (i.e, three brackets, instead of two).

A folgezettel heterarchy differs from a traditional “category tree” in two key ways:

• It is built organically over time based on the connections formed, instead of being pre-defined.
• A note can have multiple parents.

The heterarchy is displayed in the following places

• z-index: Full folgezettel heterarchy of the zettelkasten.
• : Subset of the above, branching off to the zettel.
