 ## What You Get
 
 - A **5h** bar for your current 5-hour Claude usage window
 - A **7d** bar for your current 7-day window
+- Optional Codex usage bars alongside Claude Code
 - A live countdown until each limit resets
 - A small native widget that lives directly in the Windows taskbar
-- A **system tray icon** showing your usage percentage as a color-coded badge
+- System tray icon badges showing your enabled model usage percentage
 - Left-click the tray icon to toggle the taskbar widget on or off
-- Right-click options for refresh, update frequency, language, startup, and updates
+- Right-click options for refresh, displayed models, update frequency, language, startup, and updates
 
 ## Who This Is For
 
 This app is for Windows users who already have **Claude Code (CLI or App) installed and signed in**.
 
+Codex support is optional. To show Codex usage, install and sign in to the Codex CLI, then enable Codex from the right-click **Models** menu.
+
 It works best if you want a simple "how close am I to the limit?" display that is always visible.
 
 ## Requirements
 
 - Windows 10 or Windows 11
 - Claude Code (CLI or App) installed and authenticated
+- Optional: Codex CLI installed and authenticated, if you want Codex usage
 
 If you use Claude Code through WSL, that is supported too. The monitor can read your Claude Code credentials from Windows or from your WSL environment.

+
+Use the right-click **Models** menu to choose what the widget displays:
+
+- **Claude Code** is enabled by default
+- **Codex** can be enabled alongside Claude Code or shown by itself
+
+When both models are shown, each model has its own usage bar and matching usage text color.

+If both Claude Code and Codex are enabled, the app shows two tray icons: one for Claude Code and one for Codex. If only one model is enabled, it shows one tray icon.

+The Claude Code tray icon uses the same warm usage colors as the Claude bar. The Codex tray icon uses a black and white badge style.
