 In Neovim, [lazy.nvim](https://github.com/folke/lazy.nvim) is probably the most popular plugin manger.
 To install VimTeX, add a plugin spec similar to this:
+
 ```lua
 {
   "lervag/vimtex",
   lazy = false,     -- we don't want to lazy load VimTeX
   -- tag = "v2.15", -- uncomment to pin to a specific release
   init = function()
-    -- VimTeX configuration goes here
+    -- VimTeX configuration goes here, e.g.
+    vim.g.vimtex_view_method = "zathura"
   end
 }
 ```
 
+VimTeX is mostly implemented with Vimscript and is configured with the
+classical vimscript variable convention like `g:vimtex_OPTION_NAME`. Nowadays,
+Neovim is often configured with Lua, thus some users may be interested in
+reading `:help lua-vimscript`.
