 The [markdown-mode](https://github.com/jrblevin/markdown-mode) package provides a major mode for Emacs for syntax highlighting, editing commands, and preview support for Markdown documents. It supports core Markdown syntax as well as extensions like GitHub Flavored Markdown (GFM).

 This configuration sets up `markdown-mode` with deferred loading to improve startup performance. The `:commands` and `:mode` keywords ensure that the mode is loaded only when needed—for example, when opening `.md`, `.markdown`, or `README.md` files. Files named `README.md` are specifically associated with `gfm-mode`, which is for GitHub Flavored Markdown syntax. The `markdown-command` variable is set to `"multimarkdown"` to specify the Markdown processor used for previews and exports. Additionally, a keybinding (`C-c C-e`) is defined in `markdown-mode-map` to invoke `markdown-do`, which can be customized to perform common Markdown-related actions.
 
+### Tree-sitter Integration (Better Syntax Highlighting)
+
+Tree-sitter in Emacs is an incremental parsing system introduced in Emacs 29 that provides precise, high-performance syntax analysis and highlighting by constructing concrete syntax trees from source code. It supports a broad set of programming languages, including Bash, C, C++, C#, CMake, CSS, Dockerfile, Go, Java, JavaScript, JSON, Python, Rust, TOML, TypeScript, YAML, Elisp, Lua, Markdown, and many others. Unlike traditional font-lock, which relies on regular expressions, Tree-sitter uses formal grammar definitions to build real-time parse trees, enabling accurate syntax highlighting, structural navigation, code folding, and foundational support for advanced editing features like refactoring.
+
+The configuration below enables Tree-sitter support using the [treesit-auto](https://github.com/renzmann/treesit-auto) package. Setting `treesit-auto-add-to-auto-mode-alist` to `'all` ensures that all available Tree-sitter modes are automatically activated for their corresponding file types. Enabling `global-treesit-auto-mode` applies this behavior globally, improving syntax accuracy and consistency across supported languages.
+
+To enable Tree-sitter, add the following to your `~/.emacs.d/post-init.el`:
+
+```elisp
+(use-package treesit-auto
+  :ensure t
+  :custom
+  (treesit-auto-install 'prompt)
+  :config
+  (treesit-auto-add-to-auto-mode-alist 'all)
+  (global-treesit-auto-mode))
+```

 ### Inhibit the mouse
 
 The [inhibit-mouse](https://github.com/jamescherti/inhibit-mouse.el) package disables mouse input in Emacs.
