 This repo is meant to be used as a starting point for a user's own configuration; remove the things you don't use and add what you miss. This configuration serves as the reference configuration for the [lspconfig wiki](https://github.com/neovim/nvim-lspconfig/wiki).
 
 ### Installation
+
 * Backup your previous configuration
 * Copy and paste the kickstart.nvim `init.lua` into `$HOME/.config/nvim/init.lua`
 * start neovim (`nvim`) and run `:PackerInstall`, ignore any error message about missing plugins, `:PackerInstall` will fix that shortly.
 * restart neovim
 
+### Configuration
+
+You could directly modify the `init.lua` file with your personal customizations. This option is the most straightforward, but if you update your config from this repo, you may need to reapply your changes.
+
+An alternative approach is to create a separate `custom.plugins` module to register your own plugins. In addition, you can handle further customizations in a `after/plugin/defaults.lua` file. See the following examples for more information. Leveraging these files should make upgrading to a newer version of this repo easier. 
+
+#### Example `plugins.lua`
+
+The following is an example of a `plugins.lua` file (located at `$HOME/.config/nvim/lua/custom/plugins.lua`) where you can register you own plugins. 
+
+```lua
+return function(use)
+  use({
+    "folke/which-key.nvim",
+      config = function()
+        require("which-key").setup({})
+      end
+  })
+end
+```
+
+#### Example `defaults.lua`
+
+The following is an example `defaults.lua` file (localed at `$HOME/.config/nvim/after/plugin/defaults.lua`) where you can define your own options, keymaps, autogroups, and more.
+
+```lua
+vim.opt.relativenumber = true
+
+vim.keymap.set('n', '<leader>sr', require('telescope.builtin').resume, { desc = '[S]earch [R]esume' })
+```

 ### Contribution
 
 Pull-requests are welcome. The goal of this repo is not to create a neovim configuration framework, but to offer a starting template that shows, by example, available features in neovim. Some things that will not be included:
