+### Configuration Options
+
+- **General**
+  - `BaseDir`: Directory where downloaded files will be saved.
+  - `Format`: Output format for the downloaded files (e.g., `mkv`, `mp4`).
+  - `TempBaseDir`: Temporary directory for intermediate files.
+  - `EnableConsole`: Boolean to enable or disable console output.
+
+- **WatchFolder**
+  - `Path`: Directory to watch for new `.drmd` files.
+  - `PollingInterval`: Interval in seconds for polling the watch folder.
+  - `UsePolling`: Boolean to enable or disable folder polling.
+  - `UseInotify`: Boolean to enable or disable inotify for file watching.
+
+- **N_m3u8DLRE**
+  - `Path`: Path to the N_m3u8DL-RE executable.
+
+### Environment Variable Overrides
+
+You can override the configuration options using environment variables. The following environment variables are supported:
+
+- `BASE_DIR`: Overrides `General.BaseDir`
+- `FORMAT`: Overrides `General.Format`
+- `TEMP_BASE_DIR`: Overrides `General.TempBaseDir`
+- `WATCHED_FOLDER`: Overrides `WatchFolder.Path`
+- `USE_POLLING`: Overrides `WatchFolder.UsePolling` (set to `true` or `false`)
+- `USE_INOTIFY`: Overrides `WatchFolder.UseInotify` (set to `true` or `false`)
+- `POLLING_INTERVAL`: Overrides `WatchFolder.PollingInterval`
