+## Read Expression File
+
+```bash
+cargo run --example read_file
+```
+
+This example reads an exported expression `.ron` file and returns `NoiseFn` implementations with
+different variable values. You may export any expression in the desktop app by right-clicking on the
+node.
+
+## Complex Planet (stress test)
+
+The included `complexplanet.ron` file is a project file which may be opened in the desktop app. It
+is a recreation of
+[`complexplanet.rs`](https://github.com/Razaekel/noise-rs/blob/develop/examples/complexplanet.rs)
+from [Noise-rs](https://github.com/Razaekel/noise-rs).
+
+Opening the project will take a few minutes while all the preview images are recreated. Any changes
+to the final nodes will also cause lots of computation and slow down the UI a little, although it
+should remain responsive.
+
+> [!NOTE]
+> Future changes to `noise_gui` will focus on making files of this size easier to understand and
+> edit.
+
+Once loaded it should look like this:
