what the last version of Spectrum that worked on their NUC with Nvidia
graphics is.

+# Contributing to this documentation {#chap-contributing}
+
+The sources of the Nixpkgs manual are in the [doc](https://github.com/NixOS/nixpkgs/tree/master/doc) subdirectory of the Nixpkgs repository. The manual is still partially written in DocBook but it is progressively being converted to [Markdown](#sec-contributing-markup).
+
+You can quickly check your edits with `make`:
+
+```ShellSession
+$ cd /path/to/nixpkgs/doc
+$ nix-shell
+[nix-shell]$ make
+```
+
+If you experience problems, run `make debug` to help understand the docbook errors.
+
+After making modifications to the manual, it's important to build it before committing. You can do that as follows:
+
+```ShellSession
+$ cd /path/to/nixpkgs/doc
+$ nix-shell
+[nix-shell]$ make clean
+[nix-shell]$ nix-build .
+```
+
+If the build succeeds, the manual will be in `./result/share/doc/nixpkgs/manual.html`.
+
+## Syntax {#sec-contributing-markup}
+
+As per [RFC 0072](https://github.com/NixOS/rfcs/pull/72), all new documentation content should be written in [CommonMark](https://commonmark.org/) Markdown dialect.
+
+Additionally, the following syntax extensions are currently used:
+
+- []{#ssec-contributing-markup-anchors}
+  Explicitly defined **anchors** on headings, to allow linking to sections. These should be always used, to ensure the anchors can be linked even when the heading text changes, and to prevent conflicts between [automatically assigned identifiers](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/auto_identifiers.md).
+
+  It uses the widely compatible [header attributes](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/attributes.md) syntax:
+
+  ```markdown
+  ## Syntax {#sec-contributing-markup}
+  ```
+
+- []{#ssec-contributing-markup-anchors-inline}
+  **Inline anchors**, which allow linking arbitrary place in the text (e.g. individual list items, sentences…).
+
+  They are defined using a hybrid of the link syntax with the attributes syntax known from headings, called [bracketed spans](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/bracketed_spans.md):
+
+  ```markdown
+  - []{#ssec-gnome-hooks-glib} `glib` setup hook will populate `GSETTINGS_SCHEMAS_PATH` and then `wrapGAppsHook` will prepend it to `XDG_DATA_DIRS`.
+  ```
+
+- []{#ssec-contributing-markup-automatic-links}
+  If you **omit a link text** for a link pointing to a section, the text will be substituted automatically. For example, `[](#chap-contributing)` will result in [](#chap-contributing).
+
+  This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/using/syntax.html#targets-and-cross-referencing).
+
+- []{#ssec-contributing-markup-inline-roles}
+  If you want to link to a man page, you can use `` {manpage}`nix.conf(5)` ``, which will turn into {manpage}`nix.conf(5)`.
+
+  The references will turn into links when a mapping exists in {file}`doc/build-aux/pandoc-filters/link-unix-man-references.lua`.
+
+  This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/syntax/syntax.html#roles-an-in-line-extension-point). Though, the feature originates from [reStructuredText](https://www.sphinx-doc.org/en/master/usage/restructuredtext/roles.html#role-manpage) with slightly different syntax.
+
+- []{#ssec-contributing-markup-admonitions}
+  **Admonitions**, set off from the text to bring attention to something.
+
+  It uses pandoc’s [fenced `div`s syntax](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/fenced_divs.md):
+
+  ```markdown
+  ::: {.warning}
+  This is a warning
+  :::
+  ```
+
+  which renders as
+
+  > ::: {.warning}
+  > This is a warning.
+  > :::
+
+  The following are supported:
+
+    - [`caution`](https://tdg.docbook.org/tdg/5.0/caution.html)
+    - [`important`](https://tdg.docbook.org/tdg/5.0/important.html)
+    - [`note`](https://tdg.docbook.org/tdg/5.0/note.html)
+    - [`tip`](https://tdg.docbook.org/tdg/5.0/tip.html)
+    - [`warning`](https://tdg.docbook.org/tdg/5.0/warning.html)
+
+- []{#ssec-contributing-markup-definition-lists}
+  [**Definition lists**](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/definition_lists.md), for defining a group of terms:
+
+  ```markdown
+  pear
+  :   green or yellow bulbous fruit
+
+  watermelon
+  :   green fruit with red flesh
+  ```
+
+  which renders as
+
+  > pear
+  > :   green or yellow bulbous fruit
+  >
+  > watermelon
+  > :   green fruit with red flesh
+
