-The Docker Compose files are populated with values from your `.env`, so you don't need to edit the Docker Compose files manually.
+If a variable isn't set, OpenRAG uses default or fallback values where available.
+Not all variables have default values, and errors can occur if required variables aren't set.
+Default values can be found in the reference tables on this page and in [`config_manager.py`](https://github.com/langflow-ai/openrag/blob/main/src/config/config_manager.py), [`settings.py`](https://github.com/langflow-ai/openrag/blob/main/src/config/settings.py), and [`logging_config.py`](https://github.com/langflow-ai/openrag/blob/main/src/utils/logging_config.py).
 
-Environment variables always take precedence over other variables.
+You can [temporarily set Langflow variables at runtime](#modify-a-flow-at-runtime).
+However, these temporary overrides don't overlap with most OpenRAG environment variables.
+The only exceptions are flow-level Langflow settings, such as the language model used in a flow.
 
-### Set environment variables {#set-environment-variables}
+## Edit the `.env` file {#set-environment-variables}
 
-Environment variables are either mutable or immutable.
+During [installation](/install-options), an initial `.env` file is created automatically or manually.
+You can edit this file to change OpenRAG configuration settings after installation.
 
-If you edit mutable environment variables, you can apply the changes by stopping and restarting the OpenRAG services after editing the `.env` file:
+Each OpenRAG environment variable is either mutable or immutable.
+This determines the actions you must take to apply changes after editing the `.env` file:
 
-1. [Stop the OpenRAG services](/manage-services).
+* **Mutable environment variables**: You can apply changes to mutable environment variables by [stopping and restarting the OpenRAG services](/manage-services) after editing the `.env` file.
 
-2. Edit your `.env` file.
+* **Immutable environment variables**: You must [redeploy OpenRAG](/reinstall) with your modified `.env` file if you change immutable environment variables.
 
-3. [Restart the OpenRAG services](/manage-services).
-
-If you edit immutable environment variables, you must [redeploy OpenRAG](/reinstall) with your modified `.env` file.
-For example, with self-managed services, do the following:
-
-1. Stop the deployment:
-
-   ```bash title="Docker"
-   docker compose down
-   ```
-
-   ```bash title="Podman"
-   podman compose down
-   ```
-
-2. Edit your `.env` file.
-
-3. Redeploy OpenRAG:
-
-   <PartialDockerComposeUp />
-
-4. Restart the Docling service.
-
-5. Launch the OpenRAG app, and then repeat the [application onboarding process](/install#application-onboarding). The values in your `.env` file are automatically populated.

-## Langflow runtime overrides
-
-You can modify [flow](/agents) settings at runtime without permanently changing the flow's configuration.

-Runtime overrides are implemented through _tweaks_, which are one-time parameter modifications that are passed to specific Langflow components during flow execution.
