 ## Step-by-Step Installation
 
+### Step 0 — Install Xcode Command Line Tools
+
+On a fresh Mac, you need Apple's developer command line tools before anything else
+(`git`, `cc`, build headers). Install them with:
+
+```bash
+xcode-select --install
+```
+
+A GUI installer will pop up — accept and let it finish. If the tools are already
+installed the command instead prints
+`xcode-select: error: command line tools are already installed, use "Software Update" to install updates`
+and exits non-zero, which is fine — you can move on.
+
+!!! note "Homebrew will ask too"
+    Step 1's Homebrew installer also requests the Command Line Tools if it doesn't see
+    them. Running `xcode-select --install` upfront avoids the second prompt and confirms
+    the tools landed correctly.
+
+---
+
 ### Step 1 — Install Homebrew
 
 Homebrew is the standard macOS package manager. Everything else in this guide is installed
