 Stirling PDF offers various other customisation options, such as:
 
-### Defaulting Language
+## Static File Overrides
+
+You can override static files (logos, images, favicons, etc.) by placing custom versions in the `customFiles/static/` directory.
+
+### How It Works
+
+Stirling-PDF checks for files in this order:
+1. **First:** `customFiles/static/` (your custom files)
+2. **Fallback:** Built-in static files embedded in the application
+
+This means you can replace any static resource by placing a file with the matching path in `customFiles/static/`.
+
+### Finding File Paths to Override
+
+Static files in the application come from the `frontend/public/` folder in the source code. The mapping is direct:
+
+**Frontend source → Your override path:**
+- `frontend/public/favicon.svg` → `customFiles/static/favicon.svg`
+- `frontend/public/modern-logo/logo.svg` → `customFiles/static/modern-logo/logo.svg`
+- `frontend/public/classic-logo/logo.svg` → `customFiles/static/classic-logo/logo.svg`
+
+**To see what files you can override:**
+1. Browse the [frontend/public folder on GitHub](https://github.com/Stirling-Tools/Stirling-PDF/tree/main/frontend/public)
+2. Match the directory structure in your `customFiles/static/` folder
+
+Common files you might want to override:
+
+**Favicons & Icons:**
+- `favicon.svg`, `favicon.ico` - Browser favicons
+- `apple-touch-icon.png` - iOS home screen icon
+- `android-chrome-192x192.png` - Android icon (192x192)
+- `android-chrome-512x512.png` - Android icon (512x512)
+
+**Logo Variants (Both classic-logo/ and modern-logo/):**
+
+Both logo directories contain the same file structure - just replace `classic-logo/` or `modern-logo/` with whichever style you're using:
+
+- `{style}/StirlingPDFLogoBlackText.svg` - Logo with black text (light mode)
+- `{style}/StirlingPDFLogoWhiteText.svg` - Logo with white text (dark mode)
+- `{style}/StirlingPDFLogoGreyText.svg` - Logo with grey text
+- `{style}/StirlingPDFLogoNoTextDark.svg` - Logo without text (dark variant)
+- `{style}/StirlingPDFLogoNoTextLight.svg` - Logo without text (light variant)
+- `{style}/logo-tooltip.svg` - Small logo for tooltips
+- `{style}/favicon.ico` - Style-specific favicon
+- `{style}/logo192.png`, `{style}/logo512.png` - PNG versions at different sizes
+- `{style}/Firstpage.png` - First page preview image
+
+Where `{style}` is either `classic-logo` or `modern-logo` depending on your logo style setting:
+
+**Settings file (configs/settings.yml):**
+```yaml
+ui:
+  logoStyle: classic  # Options: 'classic' or 'modern'
+```
+
+**Environment variable (Docker):**
+```bash
+UI_LOGOSTYLE=classic
+```
+
+**In-app configuration:**
+Settings → UI → Logo Style (requires login enabled)
+
+**Other Assets:**
+- `moon.svg` - Dark mode toggle icon
+- `robots.txt` - Search engine directives
+- `manifest.json`, `manifest-classic.json` - Web app manifests
+- Images, fonts, and locales
+
+### Example: Custom Favicon
+
+```bash
+# Your directory structure
+customFiles/
+  └── static/
+      ├── favicon.svg
+      └── favicon.ico
+```
+
+Docker compose:
+```yaml
+volumes:
+  - ./customFiles:/customFiles:rw
+```
+
+Restart the container - your custom favicons will be used!
+
+### Example: Custom Logo (Simple)
+
+```bash
+customFiles/
+  └── static/
+      └── classic-logo/
+          └── StirlingPDFLogoBlackText.svg
+```
+
+This overrides the classic logo with black text (used in light mode).
+
+**Important:** Make sure your logo style is set to `classic` in your configuration:
+```yaml
+ui:
+  logoStyle: classic  # Must match the directory you're overriding!
+```
+
+Or via environment variable:
+```bash
+UI_LOGOSTYLE=classic
+```
+
+If you have `logoStyle: modern` set, override files in `modern-logo/` instead!
+
+### Example: Complete Branding Customization
+
+To fully rebrand Stirling-PDF with your company logo, override multiple variants:
+
+```bash
+customFiles/
+  └── static/
+      ├── favicon.svg                                    # Main favicon
+      ├── favicon.ico                                    # Legacy favicon
+      └── classic-logo/                                  # Or modern-logo/ if using modern style
+          ├── StirlingPDFLogoBlackText.svg              # Light mode with text
+          ├── StirlingPDFLogoWhiteText.svg              # Dark mode with text
+          ├── StirlingPDFLogoNoTextLight.svg            # Light mode icon only
+          ├── StirlingPDFLogoNoTextDark.svg             # Dark mode icon only
+          ├── logo-tooltip.svg                          # Small icon
+          ├── favicon.ico                               # Style-specific favicon
+          └── Firstpage.png                             # Homepage preview
+```
+
+**Important:** Set your logo style to match the directory:
+```yaml
+ui:
+  logoStyle: classic  # Use 'classic' if overriding classic-logo/, 'modern' if overriding modern-logo/
+```
+
+Or via environment variable: `UI_LOGOSTYLE=classic`
+
+**Tips:**
+- For consistent branding across light/dark modes, provide both:
+  - `StirlingPDFLogoBlackText.svg` (shows on light backgrounds)
+  - `StirlingPDFLogoWhiteText.svg` (shows on dark backgrounds)
+- You can also configure this in-app: Settings → UI → Logo Style (if you have login enabled)
+
+### Advanced: Overriding Built Files (HTML, JS, CSS)
+
+**⚠️ For developers only!**
+
+Files like `index.html`, JavaScript bundles, and CSS are **generated** by the build process from `frontend/src/`. To override these:
+
+1. Clone the Stirling-PDF repository
+2. Make your changes to the React source code in `frontend/src/`
+3. Build the frontend: `npm run build` (from the `frontend/` directory)
+4. The built files appear in `frontend/dist/`
+5. Copy the specific files you want to override to `customFiles/static/` matching the path structure
+
+**Example:** To override `index.html`:
+```bash
+# After building the frontend
+cp frontend/dist/index.html customFiles/static/index.html
+```
+
+**Warning:** Built files may include hashed filenames (e.g., `assets/index-abc123.js`) that change with each build. Overriding these requires matching the exact filename from your build and is not recommended for most users.
