+Both `bootstrap_project` and `configure_project` handle the setup of a Kedro project, but there are subtle differences: `bootstrap_project` is used for project mode, and `configure_project` is used for packaged mode.
+
+Kedro's CLI runs the functions at startup as part of `kedro run` so in most cases you don't need to call these functions. If you want to [interact with a Kedro project programatically in an interactive session such as Notebook](../notebooks_and_ipython/kedro_and_notebooks.md#reload_kedro-line-magic), use `%reload_kedro` line magic with Jupyter or IPython. Only use these functions directly if none of these methods work.
+
+### `bootstrap_project`
+
+This function uses `configure_project`, and additionally reads metadata from `pyproject.toml` and adds the project root to `sys.path` so the project can be imported as a Python package. It is typically used to work directly with the source code of a Kedro project.
+
+### `configure_project`
+
+This function reads `settings.py` and `pipeline_registry.py` and registers the configuration before Kedro's run starts. If you have a packaged Kedro project, you only need to run `configure_project` before executing your pipeline.
