+# Documentation
+
+We use [Sphinx](https://www.sphinx-doc.org) to generate Meshroom's documentation.
+
+To install all the requirements for building the documentation, simply run: 
+```bash
+pip install sphinx sphinx-rtd-theme myst-parser
+```
+
+> Note: since Sphinx will import the entire `meshroom` package, all requirements for Meshroom must also be installed
+
+To generate the documentation, go to the `docs` folder and run the Sphinx makefile: 
+```bash
+cd meshroom/docs
+make html
+```
+
+To access the documentation, simply go to `meshroom/docs/build/html` and open `index.html` in a browser.
