   * There is a cache so that source services won't ban you even if you hammer the rss-bridge with requests. Each bridge has a different duration for the cache. The `cache` subdirectory will be automatically created and cached objects older than 24 hours get purged.
   * To implement a new rss-bridge, [follow the specifications](CREATE_BRIDGE.md) and take a look at existing bridges for examples.
+  * To enable debug mode (disabling cache and enabling error reporting), create an empty file named `DEBUG` in the root directory (next to `index.php`).
