 ## Shortcut Task Commands
 
-To be able to run shortcut task commands, first install the Poetry plugin [`poethepoet`](https://poethepoet.natn.io/index.html):
-
-```console
-poetry self add 'poethepoet[poetry_plugin]'
-```

-> [!NOTE]
-> Upon the release of Poetry [v2.0.0](https://github.com/orgs/python-poetry/discussions/9793#discussioncomment-11043205), Poetry will automatically support bootstrap installation of [project-specific plugins](https://github.com/python-poetry/poetry/pull/9547) and installation of the task runner will become automatic for this project.
-> The `pyproject.toml` syntax will be:
-> 
-> ```toml
-> [tool.poetry]
-> requires-poetry = ">=2.0"
-> 
-> [tool.poetry.requires-plugins]
-> poethepoet = ">=0.29"
-> ```
