+# Copernicus Climate Data Store (C3S)
+
+This tool allows you to retrieve [Copernicus Climate Data Store (C3S)](https://cds.climate.copernicus.eu/#!/home).
+
+- Any user willing to use this tool needs to [create a new account](https://cds.climate.copernicus.eu/user/register?destination=%2F%23!%2Fhome).
+- Compose your request directly on C3S and copy/paste it in the input field "Request"
+- Users need to add their CDS API Key to Galay (see below). Documentation on where to get the CDS API key can be found [here](https://cds.climate.copernicus.eu/api-how-to).
+- 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.
+
+## Set up user credentials on Galaxy
+
+To enable users to set their credentials and provide their CDS API Key for this tool,
+make sure the file `config/user_preferences_extra.yml` has the following section:
+
+```
+    c3s_account:
+        description: Your CDS API Key (Copernicus Climate Change Service API Key)
+        inputs:
+            - name: c3s_cds_apikey
+              label: C3S CDS API Key
+              type: text
