 not always the other way around! This is because the format of the coordinates
 and parameters after the URI scheme "geo:" may be invalid!
 
+### Feature: `serde`
+
+If you enable the `serde` feature, [`GeoUri`] will implement
+[`serde::Serialize`](https://docs.rs/serde/1/serde/trait.Serialize.html) and
+[`serde::Deserialize`](https://docs.rs/serde/1/serde/trait.Deserialize.html).
+See the [serde](https://serde.rs) documentation for more information.
