 # Graph view
 
-A zettelkasten is a [directed graph](https://en.wikipedia.org/wiki/Directed_graph), and <2017401> is a subset of this graph established by having zettels branch off to other zettels.
+A zettelkasten is a [directed graph](https://en.wikipedia.org/wiki/Directed_graph). Neuron also has the notion of <2017401>, which is a subset of this graph established by having zettels "branch off" to other zettels.
 
 ## z-index 
 
-The z-index page (at `/z-index.html`; also linked in the footer) displays your Zettelkasten folgezettel graph. Neuron detects if there are any cycles in the graph (use `cf` to resolve cycles). Then, it detects all <2012301> in the graph, and displays the <2017401> for each cluster.
+The z-index page (at `/z-index.html`; also linked in the header) displays the zettelkasten <2017401> for all <2012301> in the zettelkasten graph.
 
 ## Uplinks and Backlinks
 
-Uplinks are a kind of backlinks. Specifically an **uplink tree** of a zettel is the subset of the <2017401> which branch off to the zettel. Uplink tree is displayed above the zettel; other backlinks are displayed below.
+A backlink of a zettel is a zettel that links to it. If that link is a folgezettel link, it is called an "uplink". 
 
+An **uplink tree** of a zettel is the subset of the <2017401> which branch off to the zettel. Uplink tree is displayed above the zettel; other backlinks are displayed below.

+Use `?cf` (see <2011504?cf>) to eject something out of a zettel's uplink tree.
