+# Typst Language Pack
+
+This plugin pack does the following:
+
+-   Add `typst,vim` for syntax
+-   Add `typst_lsp` language server
+
+if you want to use typst outside a git repository, typst_lsp cannot find `root_dir`, add the following setting to `lsp.config` in your nvim config
+
+```lua
+typst_lsp = function(opts)
+  return {
+    exportPdf = "onType", -- Choose onType, onSave or never.
+    root_dir = require("lspconfig.util").root_pattern("README.md", ".git", "main.typ"),
+  }
+end,
+```
