 ### Integrations
 
 - `markdown` - uses [tree-sitter-markdown](https://github.com/MDeiml/tree-sitter-markdown) and supports any Markdown-based grammars (Quarto, VimWiki Markdown)
+- `asciidoc` - scans buffers for the [image macros](https://docs.asciidoctor.org/asciidoc/latest/macros/images/)
 - `neorg` - uses [tree-sitter-norg](https://github.com/nvim-neorg/tree-sitter-norg) (also check https://github.com/nvim-neorg/neorg/issues/971)
 - `typst` - thanks to @etiennecollin (https://github.com/3rd/image.nvim/pull/223)
 - `html` and `css` - thanks to @zuloo (https://github.com/3rd/image.nvim/pull/163)
