+In addition to the standard [CDSE services](CDSE.md) the hackathon participants can launch virtual server in the [CREODIAS](https://creodias.eu/) platform provided by CloudFerro. 
+
+For the access to the CREODIAS platform each team will receive one Keystone credential and an SSH key to be used with the pre-configured OS-GEO live server with additional services (Rstudio, JupyterHub, Shiny, Apache Superset).
+
+On the [Horizon Dashboard](https://horizon.cloudferro.com/) the participants have to use the option ***Keystone credentials*** and use the Domain ***cloud_078898*** and region ***WAW3-2***.

+After the first login the participants should be able to see the pre-launched server with GPU support. The participants from the Dashboard can terminate the preconfigured server and can launch additional service till the allowed overall limit per team:
+
+ - max 20 instances
+ - max 20 CPU cores
+ - max 50 GB RAM
+ - max 10 disk with a max 1000 GB storage in total
+ 
+ 
+From the virtual servers you can access the CDSE resources and the additional dataset which are mentioned in the Data Catalogue.
+The sample notebooks are accessible under this folder:
