+\subsection{Generating a Phylogenetic Tree}
+
+... \todosp{I guess something should be added here, right?}
+
+When a phylogenetic tree is generated, new nodes and edges get created. In
+order to give you a chance at styling them, the following styles are executed:
+
+\begin{stylekey}{/graph drawing/phylogenetic inner node}
+    The style is added every newly created inner node. In this manual, this key
+    is set to:
+    %
+\begin{codeexample}[code only]
+\pgfgdset{phylogenetic inner node/.style={
+    /tikz/.cd, draw, circle, inner sep=0pt, minimum size=5pt
+  }
+}
+\end{codeexample}
+    %
+\end{stylekey}
+
+\begin{stylekey}{/graph drawing/phylogenetic edge=\meta{length}}
+    The style is added every newly created phylogenetic edge. The \meta{length}
+    will be set to the computed evolutionary length of the edge. In this
+    manual, this key is set to:
+    %
+\begin{codeexample}[code only]
+\pgfgdset{phylogenetic edge/.style={
+    /tikz/.cd, thick, rounded corners
+  }
+}
+\end{codeexample}
