+
+# Vakit Takibi for Zen
+
+A calm, glassy Zen Browser interface inspired by the Vakit Takibi prayer-times extension.
+
+## What it changes
+
+- Gives the URL bar, sidebar and menus soft translucent surfaces.
+- Highlights the active tab with a clear accent indicator.
+- Styles toolbar controls with subtle rounded hover states.
+- Supports Zen's light and dark appearances automatically.
+- Offers four accent colors and an optional compact-tab mode.
+
+## Important
+
+This Zen Mod changes browser appearance only. Prayer-time fetching, countdowns and notifications remain part of the separate [Vakit Takibi extension](https://github.com/selimsezr/zen_salah_extension).
+
+## Manual testing
+
+Copy `chrome.css` into the `chrome/userChrome.css` file in your Zen profile and restart the browser. For live editing and profile-folder instructions, see the [Zen Browser CSS guide](https://docs.zen-browser.app/guides/live-editing).
