## registryUrls
-This is only necessary in case you need to manually configure a registry URL to use for datasource lookups. Applies to PyPI (pip) only for now. Supports only one URL for now but is defined as a list for forward compatibility.
+Usually Renovate is able to either (a) use the default registries for a datasource, or (b) automatically detect during the manager extract phase which custom registries are in use. In case there is a need to configure them manually, it can be done using this `registryUrls` field, typically using `packageUrls` like so:
+
+```json
+{
+ "packageRules": [
+ {
+ "datasources": ["docker"],
+ "registryUrls": ["https://docker.mycompany.domain"]
+ }
+ ]
+}
+```
+
+The field supports multiple URLs however it is datasource-dependent on whether only the first is used or multiple.
