+## Tree-sitter
+
+Tree-sitter is managed with `nvim-treesitter` via `vim.pack`.
+
+Installing missing parsers requires the external tools from the upstream README:
+
+- `tar`
+- `curl`
+- `tree-sitter-cli`
+- a C compiler
+
+If `tree-sitter` is on your `PATH`, startup will try to install the configured parsers if they are missing.
+
+Useful commands:
+
+```vim
+:TSUpdate
+:TSInstall lua bash json
+:TSInstallInfo
+:InspectTree
+:checkhealth vim.treesitter
+```
