+## Evcxr Integration
+
+[Evcxr][evcxr] is a Rust REPL and a [Jupyter notebook kernel][evcxr-jupyter].
+This crate integrates into Evcxr and the Jupyter notebooks using the `evcxr` feature flag, which enables native displays of tables.
+This includes support for displaying colors and various formattings.
+
+You can include prettytable as a dependency using this line:
+```
+:dep prettytable = { git = "https://github.com/phsym/prettytable-rs", package = "prettytable-rs", features = ["evcxr"] }
+```
