+**Copernicus Climate Data Store (C3S)**
+=======================================================================================================
+
+This tool is a wrapper to retrieve data from the Copernicus Climate Data Store.
+
+- It allows to retrieve data from the Copernicus climate Data Store.
+- Any user willing to use this tool needs to `create a new account <https://cds.climate.copernicus.eu/user/register?destination=%2F%23!%2Fhome>`_.
+- Set your CDS API Key via: User -> Preferences -> Manage Information"
+- Documentation on where to get the CDS API key can be found `here <https://cds.climate.copernicus.eu/api-how-to>`_.
+- Compose your request directly on C3S and copy/paste it in the input field "Request" or save it in a file.
+- Be aware that for being able to download dataset from C3S, users also need to agree to their term of use (Licence to use Copernicus Products) on the C3S website.
