+## Mutable Graphs
+
+A number of structures make it possible to create dynamically growing graphs:
+[`BTreeGraph`], [`VecGraph`] and their labeled counterparts
+[`LabeledBTreeGraph`] and [`LabeledVecGraph`]. These structures can also
+be serialized with [serde](https://crates.io/crates/serde) using the feature
+gate `serde`; [`VecGraph`]/[`LabeledVecGraph`] can also be seralized with
+[ε-serde](https://crates.io/crates/epserde).
