+👋 Welcome to Codespaces! Wait a few seconds for the Python requirements to install.
+
+📝 In the meantime, begin following the instructions in the README.
+
+🤔 If you have questions, use the GitHub Copilot "Chat" extension along the left panel (note: you may need to click the ellipses (...) to see the extension)

+# Autograding Example: Python
+This example project is written in Python, and tested with pytest.
+
+## The assignment
+The tests are failing right now because the method isn't outputting the correct string. Fixing this up will make the tests green.
+
+## Setup command
+
+See `postCreateCommand` from [`devcontainer.json`](.devcontainer/devcontainer.json).
+
+## Run command
+`pytest`
+
+## Notes
+- pip's install path is not included in the PATH var by default, so without installing via `sudo -H`, pytest would be unaccessible.
