Markdown links inside HTML

tags typically aren’t rendered as links on GitHub (the text may display literally as [Lazy.nvim](...)). Consider using plain text in the summary, or switch to an HTML anchor (<a href=...>) to ensure the link works.

Fix it @copilot

[Copilot]

Fixed in 241cdbe — replaced Markdown links in both <summary> tags with HTML <a> tags so they render correctly. Also pinned rev to "v1.0.0" for reproducibility.

[Copilot]

The Nix NVF example is fenced as lua but the snippet is Nix code. Please change the code fence language to something like nix to avoid misleading syntax highlighting/copy-paste.

[Copilot]

Using rev = "main" with fetchFromGitHub makes this example fragile: whenever the upstream main branch changes, the pinned hash will no longer match and builds will fail. Prefer pinning rev to a specific commit (and optionally updating version accordingly) so the example stays reproducible.

Suggested change

	rev = "main";
	rev = "v1.0.0";
