+# python-sat Examples
+
+Each sub-directory contains a self-contained example. The order in
+which the examples are to appear is specified in `order.json` (an
+array of directory names in the expected order).
+
+In each example directory you'll find:
+
+* `config.toml` - must conform to the specification outlined here:
+  https://docs.pyscript.net/latest/user-guide/configuration/ This is
+  parsed and ultimately turned into a JSON representation as part of
+  the package's API object.
+* `setup.py` - Python code for contextual and environmental setup,
+  NOT SEEN BY THE END USER, but is run before the `code.py` code is
+  evaluated. Allows us to create useful (IPython) shims, avoid
+  repeating boilerplate and whatnot.
+* `code.py` - the actual code added to the editor which forms the
+  practical example of using the package.
