+## S3 Usage
+
+For the usage with a AWS S3 Bucket, you just need to specify the following options:
+- provider
+- aws-access-key
+- aws-secret-key
+- bucket
+- s3-region
+
+If you specify the s3-region, you don't need to set the endpoint URL since the correct endpoint will used automatically.
+
+### Custom S3 providers
+
+To use a custom non-AWS S3 provider, you need to specify the endpoint as definied from your cloud provider.
