[Unreal/CarlaUE4/Carla/Plugins](http://carla.org/Doxygen/html/dir_8fc34afb5f07a67966c78bf5319f94ae.html) The generated documentation is available at this link **** !!! note Document updates are done automatically by GitHub. ### Create doxygen documentation !!! important [Doxygen](http://www.doxygen.nl/index.html) is required to generate the documentation and [Graphviz](https://www.graphviz.org/) for the graph drawing toolkit. 1- Install doxygen and graphviz with the following command: ```sh # linux > sudo apt-get install doxygen graphviz ``` 2- Once installed, go to the project root folder where the _Doxyfile_ file is situated and run the following command: ```sh > doxygen ``` It will start to build the documentation webpage. The resulting webpage can be found at Doxygen/html/ 3- Open _index.html_ in a browser. Now you have your local cpp documentation!
