Let’s have a look at [xclim](https://pypi.org/project/xclim/), one of our [pyOpenSci packages](https://www.pyopensci.org/python-packages.html). Notice that on the PyPI landing page you see some metadata about the package including python, maintainer information and more. PyPI is able to populate this metadata because it was defined using correct syntax and classifiers by Xclim's maintainers, [pyproject.toml file](https://github.com/Ouranosinc/xclim/blob/master/pyproject.toml). This metadata when the xclim package is built, is translated into a distribution file that allows PyPI to read the metadata and print it out on their website.

 The core information that you need in a `pyproject.toml` file in order to publish on PyPI is your **package's name**  and the **version**. However, we suggest that you flesh out your metadata early on in the `pyproject.toml` file.

 4. There is no specific order for tables in the `pyproject.toml` file. However, fields need to be placed within the correct tables. For example `requires =` always need to be in the **[build-system]** table.
 5. We suggest that you include your **[build-system]** table at the top of your `pyproject.toml` file.
