+See the [Installation and Setup](/docs/guide/install-setup) page to get started.
+
+To write a Quickshell config, start by following the
+[Guided Introduction](/docs/guide/introduction) and skimming the
+[QML Language Overview](/docs/guide/qml-language).
+
+Before continuing on your own, read the [Item Size and Position](/docs/guide/size-position)
+page to learn how to lay out elements in QML. This is significantly different
+from many other layout systems such as CSS.
+
+To learn what features Quickshell offers and how to use them, use the
+left sidebar and click through the `Quickshell Types` pages. The sidebar
+also links QtQuick's type index, which contains most of the visual elements used
+to build a UI.
+
+You may also want to check out the [Official Examples] to see some code,
+as well as review existing user configs. Do note that Quickshell has evolved
+considerably over time and most configs don't reflect current best practice.
