 We use [Sphinx](https://www.sphinx-doc.org) to generate Meshroom's documentation.
 
+## Requirements
+
 To install all the requirements for building the documentation, simply run: 
 ```bash
 pip install sphinx sphinx-rtd-theme myst-parser
 ```
 
+You also need to have [Graphviz](https://graphviz.org/) installed.
+
 > Note: since Sphinx will import the entire `meshroom` package, all requirements for Meshroom must also be installed
 
+## Build
+
 To generate the documentation, go to the `docs` folder and run the Sphinx makefile: 
 ```bash
 cd meshroom/docs
