+- **Interactive config builder** — TUI tool (`streamdeck-init`) that walks you through key setup: pick a slot, pick a module/function, customize params, choose an icon. No YAML editing required. See [Config builder](#config-builder).

+### Config builder
+
+Instead of editing YAML by hand, use the interactive TUI to configure keys:
+
+```bash
+make build-init
+./streamdeck-init
+```
+
+Or with a custom config path:
+
+```bash
+./streamdeck-init -config ~/dotfiles/.config/streamdeck-go/config.yaml
+```
+
+The tool shows your 8x4 key grid, walks you through each step, and appends the result to your config.yaml:
+
+```
