 ### Repository structure
 
 The website code is organized with a top-level `docs` folder that contains all the documentation pages as markdown files. Inside `docs` are subdirectories used to divide the docs by theme (e.g. `getting-started`,`fundamentals`, `developers` etc). Website code is in `src`, and assets including images are in `public`.
