 ## Environment Variables

- `RUSTFS_ENABLE_SCANNER` - Enable/disable background data scanner (default: true)
- `RUSTFS_ENABLE_HEAL` - Enable/disable auto-heal functionality (default: true)
+- Global configuration environment variables must use flat `RUSTFS_*` names (no module segments), such as `RUSTFS_REGION`, `RUSTFS_ADDRESS`, `RUSTFS_VOLUMES`, and `RUSTFS_LICENSE`.
+- `RUSTFS_SCANNER_ENABLED` - Enable/disable background data scanner (default: true)
+- `RUSTFS_HEAL_ENABLED` - Enable/disable auto-heal functionality (default: true)
+- Deprecated aliases (for pre-beta compatibility) are documented in [the config module README](crates/config/README.md#environment-variable-naming-conventions) and must log warnings when used.
 - For KMS tests: `NO_PROXY=127.0.0.1,localhost` and clear proxy environment variables

+## Environment Variable Naming Conventions
+
+RustFS uses a flat naming style for top-level configuration: environment variables are `RUSTFS_*` without nested module segments.
+
+Examples:
+- `RUSTFS_REGION`
+- `RUSTFS_ADDRESS`
+- `RUSTFS_VOLUMES`
+- `RUSTFS_LICENSE`
+
+Current guidance:
+- Prefer module-specific names only when they are not top-level product configuration.
+- Renamed variables must keep backward-compatible aliases until before beta.
+- Alias usage must emit deprecation warnings and be treated as transitional only.
+- Deprecated example:
+  - `RUSTFS_ENABLE_SCANNER` -> `RUSTFS_SCANNER_ENABLED`
+  - `RUSTFS_ENABLE_HEAL` -> `RUSTFS_HEAL_ENABLED`
+
