+# Doxygen Awesome
+
+[![GitHub release (latest by date)](https://img.shields.io/github/v/release/jothepro/doxygen-awesome-css)](https://github.com/jothepro/doxygen-awesome-css/releases/latest)

+![Screenshot of Doxygen Awesome CSS](img/screenshot.png)
+
+</div>
+
+**Doxygen Awesome** is a custom CSS theme for Doxygen HTML documentation with many customization options.
+
+## Motivation
+
+I really like how the Doxygen HTML documentation is structured, but IMHO it looks a bit outdated.
+
+This theme is an attempt to modernize the visuals of Doxygen without changing its overall layout too much.
+
+## Features
+
+- 🌈 Clean, modern design
+- 🚀 Highly customizable by adjusting CSS variables
+- 🧩 No changes to the HTML structure of Doxygen are required
+- 📱 Improved mobile usability
+- 🌘 Dark mode support!
+- 🥇 Works best with **Doxygen 1.9.1** - **1.9.4** and **1.9.6** - **1.14.0**
+
+## Examples
+
+Some websites using this theme:
+
+- [Documentation of this repository](https://jothepro.github.io/doxygen-awesome-css/)
+- [wxWidgets](https://docs.wxwidgets.org/3.2/)
+- [OpenCV 5.x](https://docs.opencv.org/5.x/)
+- [Zephyr](https://docs.zephyrproject.org/latest/doxygen/html/index.html)
+- [Spatial Audio Framework (SAF)](https://leomccormack.github.io/Spatial_Audio_Framework/index.html)
+- [Randolf Richardson's C++ classes](https://www.randolf.ca/c++/docs/)
+- [libsl3](https://a4z.github.io/libsl3/)
+- [DuMu<sup>x</sup>](https://dumux.org/docs/doxygen/master/)
+- [OpenRemise](https://openremise.at/)
+
+## Installation
+
+To use the theme when generating your documentation, bring the required CSS and JS files from this repository into your project.
+
+This can be done in several ways:
+
+- manually copying the files
+- adding the project as a Git submodule
+- downloading the project with CMake FetchContent
+- adding the project as an npm/xpm dependency
+- installing the theme system-wide
+
+All theme files are located in the root of this repository and start with the prefix `doxygen-awesome-`. You may not need all of them. Follow the installation instructions to determine which files are required for your setup.
+
+### Git submodule
+
+For projects that use Git, add the repository as a submodule and check out the desired release:
+
+```sh
+git submodule add https://github.com/jothepro/doxygen-awesome-css.git
+cd doxygen-awesome-css
+git checkout v2.4.1
+```
+
+### CMake with FetchContent
+
+For projects that build with CMake, the `FetchContent` module can be used to download the repository at configuration time.
+
+Add the following snippet to your `CMakeLists.txt`:
+
+```cmake
+include(FetchContent)
+FetchContent_Declare(
+    doxygen-awesome-css
+    URL https://github.com/jothepro/doxygen-awesome-css/archive/refs/heads/main.zip
+)
+FetchContent_MakeAvailable(doxygen-awesome-css)
+
+# Save the location the files were cloned into
+# This allows us to get the path to doxygen-awesome.css
+FetchContent_GetProperties(doxygen-awesome-css SOURCE_DIR AWESOME_CSS_DIR)
+
+# Generate the Doxyfile
+set(DOXYFILE_IN ${CMAKE_CURRENT_SOURCE_DIR}/doc/Doxyfile.in)
+set(DOXYFILE_OUT ${CMAKE_CURRENT_BINARY_DIR}/Doxyfile)
+configure_file(${DOXYFILE_IN} ${DOXYFILE_OUT} @ONLY)
+```
+
+This downloads the latest main (but any other revision could be used) and unpacks in the build folder. The `Doxyfile.in` can reference this location in the `HTML_EXTRA_STYLESHEET` field
+
+```text
+HTML_EXTRA_STYLESHEET  = @AWESOME_CSS_DIR@/doxygen-awesome.css
+```
+
+When the configure stage of CMake is run, the `Doxyfile.in` is rendered to Doxyfile and Doxygen can be run as usual.
+
+### npm/xpm dependency
+
+In the npm ecosystem, this project can be added as a development dependency
+to your project:
+
+```sh
+cd your-project
+npm install https://github.com/jothepro/doxygen-awesome-css#v2.4.1 --save-dev
+
+ls -l node_modules/@jothepro/doxygen-awesome-css
+```
+
+Similarly, in the [xPack](https://xpack.github.io) ecosystem, this project can be added
+as a development dependency to an [`xpm`](https://xpack.github.io/xpm/)
+managed project.
+
+### System-wide
+
+You can even install the theme system-wide by running `make install`.
+The files will be installed to `/usr/local/share/` by default,
+but you can customize the install location with `make PREFIX=/my/custom/path install`.
+
+### Choosing a layout
+
+There are two layout options. Choose one of them and configure Doxygen accordingly:
+
+<div class="tabbed">
+
+- <b class="tab-title">Base Theme</b><div class="darkmode_inverted_image">
+    ![](img/theme-variants-base.drawio.svg)
+    </div>
+    Comes with the typical Doxygen titlebar. Optionally the treeview in the sidebar can be enabled.
+
+    Required files: `doxygen-awesome.css`
+
+    Required `Doxyfile` configuration:
+    ```
+    GENERATE_TREEVIEW      = YES # optional. Also works without treeview
+    DISABLE_INDEX = NO
+    FULL_SIDEBAR = NO
+    HTML_EXTRA_STYLESHEET  = doxygen-awesome-css/doxygen-awesome.css
+    HTML_COLORSTYLE        = LIGHT # required with Doxygen >= 1.9.5
+    ```
+
+- <b class="tab-title">Sidebar-Only Theme</b><div class="darkmode_inverted_image">
+    ![](img/theme-variants-sidebar-only.drawio.svg)
+    </div>
+    Hides the top titlebar to give more space to the content. The treeview must be enabled in order for this theme to work.
+
+    Required files: `doxygen-awesome.css`, `doxygen-awesome-sidebar-only.css`
+
+    Required `Doxyfile` configuration:
+    ```
+
+    GENERATE_TREEVIEW      = YES # required!
+    DISABLE_INDEX          = NO
+    FULL_SIDEBAR           = NO
+    HTML_EXTRA_STYLESHEET  = doxygen-awesome-css/doxygen-awesome.css \
+                            doxygen-awesome-css/doxygen-awesome-sidebar-only.css
+    HTML_COLORSTYLE        = LIGHT # required with Doxygen >= 1.9.5
+    ```
+
+</div>
+
+<br>
+
+@warning
+- This theme is not compatible with the `FULL_SIDEBAR = YES` option provided by Doxygen!
+- `HTML_COLORSTYLE` must be set to `LIGHT` since Doxygen 1.9.5!
+
+### Further installation instructions
+
+- [Installing extensions](docs/extensions.md)
+- [Customizing the theme (colors, spacing, border-radius, ...)](docs/customization.md)
+- [Tips and Tricks for further configuration](docs/tricks.md)
+
+## Browser support
+
+Tested with
+
+- Chrome 140, Chrome 140 for Android, Chrome 141 for iOS
+- Safari 26, Safari for iOS 26
+- Firefox 143, Firefox 142 for Android, Firefox 143 for iOS
+- Edge 140
+- Opera One 122
+
+
+The theme does not strive to be backward compatible with (significantly) older browser versions.
