+# Arduino Neovim Configuration
+
+This directory contains the Neovim configuration for Arduino development, using [Arduino-Nvim](https://github.com/yuukiflow/Arduino-Nvim) with **LazyVim**.
+
+## Installation
+
+1. Copy `lua/plugins/arduino.lua` to your LazyVim plugins directory (e.g. `~/.config/nvim/lua/plugins/`)
+2. Copy `.arduino_config.lua` to your Arduino project root
+
+## Custom Keybinds
+
+| Keybind | Command | Description |
+|---------|---------|-------------|
+| `<Leader>mc` | `:InoCheck` | Compile and verify sketch |
+| `<Leader>mu` | `:InoUpload` | Upload sketch to board |
+| `<Leader>ms` | `:InoStatus` | Display board, port & FQBN status |
+| `<Leader>mg` | `:InoGUI` | Open GUI for board/port selection |
+| `<Leader>mm` | `:InoMonitor` | Open serial monitor |
+| `<Leader>ml` | `:InoLib` | Open library manager |
+| `<Leader>mb` | `:InoSelectBoard` | Select Arduino board |
+| `<Leader>mp` | `:InoSelectPort` | Select Arduino port |
+| `<Leader>mr` | `:InoUploadReset` | Upload with manual reset (UNO R4 WiFi) |
+
+## Board Configuration
+
+Edit `.arduino_config.lua` to set your board, port, and baudrate:
+
+```lua
+return {
+  board = "studuino:avr:studuino",
+  port = "/dev/ttyUSB0",
+  baudrate = "115200",
+}
+```
+
+## Requirements
+
+- [arduino-cli](https://arduino.github.io/arduino-cli/latest/installation/)
+- [arduino-language-server](https://github.com/arduino/arduino-language-server)
+- [Telescope.nvim](https://github.com/nvim-telescope/telescope.nvim)
+- [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig)
