 * The project uses the official s3 client, not the minio client.
-* notice the difference between *Strict methods and the normal methods.
+* **All methods throw by default** (strict mode):  - Put operations: `fastPut`, `fastPutStream` throw when file exists and overwrite is false  - Get operations: `getBucketByName`, `getFile`, `getSubDirectoryByName` throw when not found
+* **Use exists() methods to check before getting**: `bucketExists`, `fileExists`, `directoryExists`, `fastExists`
+* **No *Strict methods**: All removed (fastPutStrict, getBucketByNameStrict, getFileStrict, getSubDirectoryByNameStrict)
 * metadata is handled though the MetaData class. Important!
