 Runs [minio client](https://min.io/docs/minio/linux/reference/minio-mc.html) to upload file(s) to MinIO (self-hosted as well)
 
+## Tricky part
+_Technically_ this action can be used with different S3-compatible services, but it **needs tuning**
+
+### MinIO
+1. You should have a leading slash at the start of `target`
+2. You should include filename/dirname into `target`. If you have `source=./directory` and `target=/subdir/directory`, it would be nested - `/subdir/directory/directory` 
+
+### Yandex Cloud
+1. For Ya.Cloud you **have to** include filename/dirname into `target`, otherwise you will get an empty `target`. Example: `source=directory; target=/test` leads to empty `/test`, but `source=directory; target=/test/directory` would upload as expected.
