+# Inkscape {#sec-inkscape}
+
+[Inkscape](https://inkscape.org) is a powerful vector graphics editor.
+
+## Plugins {#inkscape-plugins}
+Inkscape plugins are collected in the [`inkscape-extensions`](https://search.nixos.org/packages?channel=unstable&type=packages&query=cudaPackages) package set.
+To enable them, use an override on `inkscape-with-extensions`:
+
+```nix
+inkscape-with-extensions.override {
+  inkscapeExtensions = with inkscape-extensions; [
+    inkstitch
+  ];
+}
+```
+
+Similarly, this works in the shell:
+
+```bash
+$ nix-shell -p 'inkscape-with-extensions.override { inkscapeExtensions = with inkscape-extensions; [inkstitch]; }'
+[nix-shell:~]$ # Ink/Stitch is now available via the extension menu
+[nix-shell:~]$ inkscape
+```
+
+All available extension can be enabled by passing `inkscapeExtensions = null;`.
+
+::: {.note}
+Loading the Inkscape extensions stand-alone (without using `override`) does not affect Inkscape at all.
