 Now, let's move to the S3 API!
+We will `s3cmd`.
+You can install it via your favorite package manager.
+Otherwise, check [their website](https://s3tools.org/s3cmd)
 
+We will configure `s3cmd` with its interactive configuration tool, be careful not all endpoints are implemented!
 
+```
+$ s3cmd --configure

+Enter new values or accept defaults in brackets with Enter.
+Refer to user manual for detailed description of all options.

+Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.

+Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
+S3 Endpoint [s3.amazonaws.com]: garage.deuxfleurs.fr

+Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
+if the target S3 system supports dns based buckets.

+s3cmd rm s3://nextcloud-bucket/hello.txt

+That's all for now!
