+# direnv.nvim
+
+Dead simple Neovim plugin to add automatic Direnv loading, inspired by
+`direnv.vim` and written in Lua.
+
+## 📦 Installation
+
+Install `direnv.nvim` with your favorite plugin manager, or clone it manually.
+You will need to call the setup function to load the plugin.
+
+## 🚀 Usage
+
+direnv.nvim will automatically call `direnv allow` in your current directory if
+`direnv` is available in your PATH, and you have auto-loading enabled.
+
+## 🔧 Configuration
+
+You can pass your config table into the `setup()` function or `opts` if you use
+`lazy.nvim`.
+
+### Options
+
+- `bin` (optional, type: string): the path to the Direnv binary. May be an
+  absolute path, or just `direnv` if it's available in your PATH. - Default:
+  `direnv`
+- `autoload_direnv` (optional, type: boolean): whether to call `direnv allow`
+  when you enter a directory that contains an `.envrc`. - Default: `false`
+- `keybindings` (optional, type: table of strings): the table of keybindings to
+  use.
+  - Default:
+    `{allow = "<Leader>da", deny = "<Leader>dd", reload = "<Leader>dr"}`
+
+#### Example:
+
+```lua
+require("direnv").setup({
+   autoload_direnv = true,
+})
+```
