+# Frequently Asked Questions (FAQ)
+
+### How can I load external python files in Pyodide?
+
+The two possible solutions are,
+
+- include these files in a python package, build a pure python wheel with
+  `python setup.py bdist_wheel` and [load it with micropip](./pypi.html#installing-wheels-from-arbitrary-urls).
+- fetch the python code as a string and evaluate it in Python,
+  ```js
+  pyodide.eval_code(pyodide.open_url('https://some_url/...'))
+  ```
+
+In both cases, files need to be served with a web server and cannot be loaded from local file system.
+
+### Why can't I load files from the local file system?
+
+For security reasons JavaScript in the browser is not allowed to load local
+data files. You need to serve them with a web-browser.
