   - *Configure the MinIO instance*: The client requires credentials to connect and interact with the MinIO instance. This configuration can be set with the following command:
 
-    ``` sh
+    ``` bash
     mc alias set myminio https://minio.gracious-varahamihira6.im.grycap.net YOUR-ACCESS-KEY YOUR-SECRET-KEY

For a complete list of available commands and their usage, refer to the [MinIO client reference](https://min.io/docs/minio/linux/reference/minio-mc.html#command-quick-reference). The following example demonstrates a PUT operation, where a file is uploaded to a specific folder within a bucket.

   mc cp /path/to/your/images/*.jpg myminio/fish-detector/input/
   ```
