+## Custom frontend
+To load a custom frontend you need to specify its path either in the config file ([see config file](#config-file)) or via flags.
+
+The frontend needs to follow this structure:
+```
+path/to/my/frontend
+├── assets
+│   ├── js-chunk-1.js (example)
+│   ├── js-chunk-2.js (example)
+│   ├── style.css (example)
+└── index.html
+```
+
+`assets` is where the resources will be loaded.  
+`index.html` is the entrypoint.
