 ## Features
 
 - Define your keymaps, commands, `augroup`/`autocmd`s, and even arbitrary Lua functions to run on the fly, as simple Lua tables, then bind them with `legendary.nvim`
-- Integration with [which-key.nvim](https://github.com/folke/which-key.nvim), use your existing `which-key.nvim` tables with `legendary.nvim`
-- Integration with [lazy.nvim](https://github.com/folke/lazy.nvim), automatically load keymaps defined via `lazy.nvim`'s `keys` property on plugin specs
+- Integration with [which-key.nvim](https://github.com/folke/which-key.nvim), use your existing `which-key.nvim` tables with `legendary.nvim` (see [extensions](./doc/EXTENSIONS.md#which-keynvim))
+- Integration with [lazy.nvim](https://github.com/folke/lazy.nvim), automatically load keymaps defined via `lazy.nvim`'s `keys` property on plugin specs (see [extensions](./doc/EXTENSIONS.md#lazynvim))
 - Execute normal, insert, and visual mode keymaps, commands, autocommands, and Lua functions when you select them
 - Show your most recently executed items at the top when triggered via `legendary.nvim` (can be disabled via config)
 - Uses `vim.ui.select()` so it can be hooked up to a fuzzy finder using something like [dressing.nvim](https://github.com/stevearc/dressing.nvim) for a VS Code command palette like interface

 ### `Which-Key.nvim`
 
 Automatically load key mappings defined by [which-key.nvim](https://github.com/folke/which-key.nvim) into `legendary.nvim`.
+For `auto_register` to work, `which-key.nvim` must be loaded on `runtimepath` before `legendary.nvim` initializes,
+but `legendary.nvim` must initialize the extension before `require('which-key').register()` is called. Alternatively,
+you can just pass your `which-key` tables to `legendary` directly.
