## Log verbosity levels

If you wish to see more logs, simply set the `LOG_LEVEL` to the desired level. Here a list with some use case:

|  Levels  | Use case                                                                                                                               | Examples                                                                                                          |

## Development

For local development, create a new virtual environment and activate it. That can be done with Python `venv` module.

```bash
$ python -m venv venv
$ source venv/bin/activate
```

Once the virtual environment is activated, install `python-bufflog` locally:

```bash
$ pip install -e .
```
