# Settings

This reference is built directly from `gunicorn.config.KNOWN_SETTINGS` and is

regenerated during every documentation build.

!!! note
|
|
Settings can be provided through the `GUNICORN_CMD_ARGS` environment
|
|
variable. For example:
|
|
|
|
```console
|
|
$ GUNICORN_CMD_ARGS="--bind=127.0.0.1 --workers=3" gunicorn app:app
|
|
```
|
|
|
|
_Added in 19.7._
