 Just making the plugin to your Neovim configuration available might not always
 be enough. In that case, you can write custom lua config using either
-`config.vim.extraPlugins` (which has the `setup` field) or
-`config.vim.luaConfigRC`. The first option uses an attribute set, which maps DAG
-section names to a custom type, which has the fields `package`, `after`,
-`setup`. They allow you to set the package of the plugin, the sections its setup
-code should be after (note that the `extraPlugins` option has its own DAG
-scope), and the its setup code respectively. For example:
+`config.vim.lazy.plugins.*.setupOpts` `config.vim.extraPlugins.*.setup` or
+`config.vim.luaConfigRC`.
+
+The first option uses an extended version of `lz.n`'s PluginSpec. `setupModule`
+and `setupOpt` can be used if the plugin uses a `require('module').setup(...)`
