 # valw
 
-macOS-style screenshots for [niri](https://github.com/YaLTeR/niri) on
-Wayland: the whole screen, a region, a window, a zoomable freeze-frame, a
-Cmd+Shift+5-style toolbar, a floating preview you can drag into other apps,
-and a built-in markup editor. Written in Rust, packaged with Nix.

-## The overview backdrop
 
-`valw backdrop` draws a slow liquid-paint background, coloured from the
-wallpaper (via Noctalia, if it runs), behind niri's overview. It only draws
-while the overview shows it. Start it with niri and place it in the
-backdrop:
-
-```kdl
-spawn-at-startup "valw" "backdrop"
-
-layer-rule {
-    match namespace="^valw-backdrop$"
-    place-within-backdrop true
-}
-```
-
-With Noctalia, turn its own backdrop off (`[backdrop] enabled = false`).
-Colours elsewhere (the region dim, the window picker's fallback) follow
-Noctalia's current community palette when there is one.
-
-## Noctalia
-
-With [Noctalia](https://noctalia.dev), valw comes as a plugin: a camera
-button on the bar (left click: the toolbar, right click: a region shot),
-the toolbar as a Noctalia panel and a control-center tile. Noctalia draws
-them, so they follow your Noctalia theme.
-
-```nix
-programs.valw.noctalia.enable = true;
-```
-
-Then enable `elars/valw` in Noctalia, add a widget of type `elars/valw:bar`
-to a bar, and bind the toolbar:
-
-```kdl
-Mod+Shift+T { spawn "noctalia" "msg" "panel-toggle" "elars/valw:toolbar"; }
