+Language server for Arduino
+
+The `arduino-language-server` can be installed by running:
+	go get -u github.com/arduino/arduino-language-server
+
+The `arduino-cli` tools must also be installed. Follow these instructions for your distro:
+	https://arduino.github.io/arduino-cli/latest/installation/
+
+After installing the `arduino-cli` tools, follow these instructions for generating
+a configuration file:
+	https://arduino.github.io/arduino-cli/latest/getting-started/#create-a-configuration-file
+and make sure you install any relevant platforms libraries:
+	https://arduino.github.io/arduino-cli/latest/getting-started/#install-the-core-for-your-board
+
+The language server also requires `clangd` be installed. It will look for `clangd` by default but
+the binary path can be overridden if need be.
+
+After all dependencies are installed you'll need to override the lspconfig command for the
+language server in your setup function with the necessary configurations:
+
+```lua
+lspconfig.arduino_language_server.setup({
+	cmd =  {
+		-- Required
+		"arduino-language-server",
+		"-cli-config", "/path/to/arduino-cli.yaml",
+		-- Optional
+		"-cli", "/path/to/arduino-cli",
+		"-clangd", "/path/to/clangd"
+	}
+})
+```
+
+For further instruction about configuration options, run `arduino-language-server --help`.
