+## Getting Started with Poetry
+
+Make sure poetry is installed and version 2.1.1 or later.  See https://python-poetry.org/docs/.
+
+```bash
+poetry update
+poetry build
+make check
+```
+
+You should see all the unit tests pass.
+
+```bash
+poetry run manifest_writer --help
+```
+
+This command should display the help menu from the ccnpy command.  It may also display some warnings about pyproject.toml.  If you see the help menu, you are ready to proceed.
