 - `tox -e lint-some-package` to run lint checks on `some-package`
 - `tox -e generate-workflows` to run creation of new CI workflows if tox environments have been updated
 - `tox -e ruff` to run ruff linter and formatter checks against the entire codebase
+- `tox -e precommit` to run all `pre-commit` actions
 
 `ruff check` and `ruff format` are executed when `tox -e ruff` is run. We strongly recommend you to configure [pre-commit](https://pre-commit.com/) locally to run `ruff` automatically before each commit by installing it as git hooks. You just need to [install pre-commit](https://pre-commit.com/#install) in your environment:
 
 ```console
-$ pip install pre-commit -c dev-requirements.txt
+pip install pre-commit -c dev-requirements.txt
 ```
 
 and run this command inside the git repository:
 
 ```console
-$ pre-commit install
+pre-commit install
 ```
 
+### Virtual Environment
+
+You can also create a single virtual environment to make it easier to run local tests.
+
+For that, you'll need to install [`uv`](https://docs.astral.sh/uv/getting-started/installation/).
+
+After installing `uv`, you can run the following command:
+
+```sh
+uv sync
+```
+
+This will create a virtual environment in the `.venv` directory and install all the necessary dependencies.
+
+### Public Symbols
+
 We try to keep the amount of _public symbols_ in our code minimal. A public symbol is any Python identifier that does not start with an underscore.
 Every public symbol is something that has to be kept in order to maintain backwards compatibility, so we try to have as few as possible.
