+--- jinja-lsp enhances minijinja development experience by providing Helix/Nvim users with advanced features such as autocomplete, syntax highlighting, hover, goto definition, code actions and linting.
+---
+--- The file types are not detected automatically, you can register them manually (see below) or override the filetypes:
+---
+--- ```lua
+--- vim.filetype.add {
+---   extension = {
+---     jinja = 'jinja',
+---     jinja2 = 'jinja',
+---     j2 = 'jinja',
+---   },
+--- }
+--- ```
+
+---@type vim.lsp.Config
+return {
+  name = 'jinja_lsp',
+  cmd = { 'jinja-lsp' },
+  filetypes = { 'jinja' },
+  root_markers = { '.git' },
+}
