+S3 access
+=========
+
+To share files S3 (Simple Storage Service) is used. In this tutorial we use `MinIO client <https://docs.min.io/docs/minio-client-quickstart-guide.html>` to work with it. 
+
+You can get access, browse and download files using your browser, using this link:  
+
+`ATHENA S3 Space <https://dtn01.sdcc.bnl.gov:9000/minio/eictest/ATHENA/>`_
+
+**The login and password for read access is not a secret and is available for all members** (but can't be published at open places like this site). Please ask us on 
+`#software-helpdesk Slack channel <https://eicip6.slack.com/archives/C02267ZDARF>`_ or drop an email to one of the SWG. 
+
+

+    mkdir -p $HOME/bin && mv mc $HOME/bin/mc && chmod +x  $HOME/bin/mc
+    alias mc "$HOME/bin/mc"
+    mc --autocompletion
