 ## 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.

-Already a `which-key.nvim` user? Use your existing `which-key.nvim` tables with `legendary.nvim`!
-
-There's a couple ways you can choose to do it:
-
-```lua
--- automatically register which-key.nvim tables with legendary.nvim
--- when you register them with which-key.nvim.
--- `setup()` must be called before `require('which-key).register()`
-require('legendary').setup({ which_key = { auto_register = true } })
--- now this will register them with both which-key.nvim and legendary.nvim
-require('which-key').register(your_which_key_tables, your_which_key_opts)
-
--- or, pass them through setup() directly
-require('which-key').register(your_which_key_tables, your_which_key_opts)
-require('legendary').setup({
-  which_key = {
-    mappings = your_which_key_tables,
-    opts = your_which_key_opts,
-    -- false if which-key.nvim handles binding them,
-    -- set to true if you want legendary.nvim to handle binding
-    -- the mappings; if not passed, true by default
-    do_binding = false,
-  },
-})
-
--- or, if you'd prefer to manually register with legendary.nvim
-require('which-key').register(your_which_key_tables, your_which_key_opts)
-require('legendary.util.which-key').bind_whichkey(
-  your_which_key_tables,
-  your_which_key_opts,
-  -- false if which-key.nvim handles binding them,
-  -- set to true if you want legendary.nvim to handle binding
-  -- the mappings; if not passed, true by default.
-  false,
-  -- true if you want to use item groups,
-  -- false if you want to add the items to the toplevel list
-  -- in legendary.nvim; defaults to true if omitted.
-  true,
