+
+## Usage
+For more information, see the [manual](manual.pdf)
+
+To use this package, simply import [circuiteria](https://typst.app/universe/package/circuiteria) and call the `circuit` function:
+```typ
+#import "@preview/circuiteria:0.2.0"
+#circuiteria.circuit({
+  import circuiteria: *
+  ...
+})
+```
