+# Firefox DevTools Minimalist Theme
+
+A revitalized, minimalist theme for Firefox DevTools, inspired by Zen's design. Includes CSS transitions and supports both light and dark modes.
+
+## Preview
+
+Here's a quick look at the theme:
+
+![Merged Screenshot](https://github.com/ArjiAmin/firefox-devtools/blob/main/images/screenshot_0_merged.png)
+
+## Installation
+
+1. Download or clone the repository.
+2. In Firefox/Zen browser, navigate to `about:config`, accept the risk warning, and search for `toolkit.legacyUserProfileCustomizations.stylesheets`. Ensure it's set to **true** (this should be the default in Zen).
+3. Navigate to `about:profiles` in your browser.
+4. Locate the section that says "This is the profile in use and it cannot be deleted." Find the "Root Directory" and click the **Open Folder** button.
+5. Navigate to the `chrome` folder and paste the downloaded `UserContent.css` file.
+6. Return to `about:profiles` and click "Restart normally...". After restart, open DevTools to see the applied theme.
+
+## Development
+
+If you want to customize the theme or make your own changes:
+
+1. Open DevTools by pressing `F12`.
+2. Click the three horizontal dots in the top-right corner to access Settings, or press F1.
+3. Scroll down to "Advanced settings" and enable the "Enable browser chrome and add-on debugging toolboxes" and "Enable remote debugging" checkboxes.
+4. Close and reopen DevTools.
+5. Press `Ctrl + Shift + Alt + I` to open the Browser Toolbox, which allows you to inspect the DevTools interface itself.
+6. Use the element inspector to identify elements you want to modify and test CSS changes in real-time.
+
+**Note:** Changes made directly in the Browser Toolbox are temporary. To make permanent changes, update your `UserContent.css` file with your modifications. Remember that changes to `UserContent.css` require a browser restart to take effect.
