+// This theme is inspired by https://github.com/matze/mtheme
+// The polylux-port was performed by https://github.com/Enivex
+// Some tweaks performed by https://github.com/marcothms
+
+// Create a presentation with:
+// #import "theme.typ": *
+// #show: presentation.with(
+//   author: [],
+//   title: [],
+//   occasion: [],
+//   date: [],
+//   logos: (),
+//   logo_height: 50%,
+//   footer: [],
+// )
+
+// Create sections and slides with:
+// #section("My Section")
+// #slide(title: "My Title")[
+//     Cool stuff!
+// ]
+
+// Create focus slides with
+// #focus-slide()[
+//    FOCUS!
+// ]
+
+// Add sourcecode via `codelst` with
+// #sourcecode(```rust println!("hello!")```)
