 # Environment Variable Configuration
 ## Overview
 Open WebUI provides a range of environment variables that allow you to customize and configure various aspects of the application. This page serves as a comprehensive reference for all available environment variables, including their types, default values, and descriptions.
 ## App/Backend
-Here is a list of supported environment variables used by `backend/config.py` intended to provide Open WebUI startup configurability. See also the [logging environment variables](/getting-started/logging#appbackend). There may be different defaults depending if launched directly, or via Docker.
+The following environment variables are used by `backend/config.py` to provide Open WebUI startup configurability. Please note that some variables may have different default values depending on whether you're running Open WebUI directly or via Docker. For more information on logging environment variables, see our [logging documentation](/getting-started/logging#appbackend).
 ### General
 #### `ENV`
 - Type: `str` (enum: `dev`, `prod`)
 - Options:
  - `dev` - Enables the FastAPI API docs on `/docs`

 #### `WEBUI_AUTH`
 - Type: `bool`
 - Default Setting: `True`
- Description: This setting enables or disables authentication. If set to False, authentication is disabled. However, it's important to note that turning off authentication is only possible for fresh installations without any existing users. If there are already users registered, you cannot disable authentication directly. Ensure that no users are present in the database if you intend to turn off `WEBUI_AUTH`.

    If set to `False`, authentication will be disabled for your Open WebUI instance. However,
    it's important to note that turning off authentication is only possible for fresh installations without any existing users.
