+### Overview
+
+This page documents all top-level options that don't otherwise have dedicated pages.
+
+Here are all of these options at a glance:
+
+```
+spawn-at-startup "waybar"
+spawn-at-startup "alacritty"
+
+prefer-no-csd
+
+screenshot-path "~/Pictures/Screenshots/Screenshot from %Y-%m-%d %H-%M-%S.png"
+
+environment {
+    QT_QPA_PLATFORM "wayland"
+    DISPLAY null
+}
+
+cursor {
+    xcursor-theme "breeze_cursors"
+    xcursor-size 48
+}
+
+hotkey-overlay {
+    skip-at-startup
+}
+```
+
+### `spawn-at-startup`
+
+Add lines like this to spawn processes at startup.
+
+`spawn-at-startup` accepts a path to the program binary as the first argument, followed by arguments to the program.
+
+This option works the same way as the `spawn` key binding action, so please read about all the subtleties on the [key bindings](./Configuration:-Key-Bindings.md) page.
+
+Note that running niri as a systemd session supports xdg-desktop-autostart out of the box, which may be more convenient to use.
+Thanks to this, apps that you configured to autostart in GNOME will also "just work" in niri, without any manual `spawn-at-startup` configuration.
+
+```
+spawn-at-startup "waybar"
+spawn-at-startup "alacritty"
+```
+
+### `prefer-no-csd`
+
+This flag will make niri ask the applications to omit their client-side decorations.
+
+If an application will specifically ask for CSD, the request will be honored.
+Additionally, clients will be informed that they are tiled, removing some rounded corners.
+
+With `prefer-no-csd` set, applications that negotiate server-side decorations through the xdg-decoration protocol will have focus ring and border drawn around them without a solid colored background.
+
+> [!NOTE]
+> Unlike most other options, `prefer-no-csd` currently only affects applications started *after* the config was saved.
+> This mainly has to do with niri working around a [bug in SDL2](https://github.com/libsdl-org/SDL/issues/8173) that prevents SDL2 applications from starting.
+
+```
+prefer-no-csd
+```
+
+### `screenshot-path`
+
+Set the path where screenshots are saved.
+A `~` at the front will be expanded to the home directory.
+
+The path is formatted with `strftime(3)` to give you the screenshot date and time.
+
+```
+screenshot-path "~/Pictures/Screenshots/Screenshot from %Y-%m-%d %H-%M-%S.png"
+```
+
+You can also set it to `null` to disable saving screenshots to disk.
+
+```
+screenshot-path null
+```
+
+### `environment`
+
+Override environment variables for processes spawned by niri.
+
+```
+environment {
+    // Set a variable like this:
+    // QT_QPA_PLATFORM "wayland"
+
+    // Remove a variable by using null as the value:
+    // DISPLAY null
+}
+```
+
+### `cursor`
+
+Change the theme and size of the cursor as well as set the `XCURSOR_THEME` and `XCURSOR_SIZE` environment variables.
+
+```
+cursor {
+    xcursor-theme "breeze_cursors"
+    xcursor-size 48
+}
+```
+
+### `hotkey-overlay`
+
+Settings for the "Important Hotkeys" overlay.
+
+Set the `skip-at-startup` flag if you don't want to see the hotkey help at niri startup.
+
+```
+hotkey-overlay {
+    skip-at-startup
+}
+```
