 See below for specifics of the different packages. Let's have a look at the common tooling first:
 
-* [**poetry**](https://python-poetry.org) is used for dependency management and publishing.
-  Use `poetry install --all-extras` in each package folder to install all dependencies for development.
+* [**uv**](https://docs.astral.sh/uv) is used for dependency management and publishing.
+  Use `uv sync --all-extras` in each package folder to install all dependencies for development.
   By default, this creates a [virtual environment](https://docs.python.org/3/tutorial/venv.html) for each package.
-  To run commands inside this package, prefix them with `poetry run`, e.g. `poetry run python myscript.py`,
-  or enter the virtual environment with `poetry shell`.
-  The creation of a separate environment can be disabled (e.g. if you want to manage this manually),
-  [see here for details](https://python-poetry.org/docs/configuration/#virtualenvscreate).
-  To install the preferred version for this repository, run
-  [`pip install -f requirements.txt`](https://github.com/scalableminds/webknossos-libs/blob/master/requirements.txt)
+  To run commands inside this package, prefix them with `uv run`, e.g. `uv run python myscript.py`,
+  or enter the virtual environment with `source .venv/bin/activate`.
 
   To install the dependencies for all sub-projects, run `make install`.
