To install it directly from GitHub, you can:

pip install git+https://github.com/MatthieuDartiailh/oculy

Once installed Oculy can be started by running:

python -m  oculy

When developing one probably does not want to re-build and re-install the wheel every time once they have made a change to the code, and for that one can use an editable install:

pip install -e .

This will install your package without packaging it into a file, but by referring to the source directory.

The next step is to generate distribution packages for the package. These are archives that are uploaded to PyPI and can be installed by pip. First of all, make sure you have the latest version of PyPA's build installed:

py -m pip install --upgrade build

Now run this command from the same directory where pyproject.toml is located:

python -m build --wheel

where --wheel flag is optional.

This should create a wheel named something like oculy-0.0.0-py3-none-any.whl in dist/ folder. One can install this install built distribution by frontend tool like pip.
