+### 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.
+
 ### Troubleshooting
 
 Some packages may require additional system-wide dependencies to be installed. For example, you may need to install `libpq-dev` to run the postgresql client libraries instrumentation tests or `libsnappy-dev` to run the prometheus exporter tests. If you encounter a build error, please check the installation instructions for the package you are trying to run tests for.
