Describe the bug
In section Set Up an index-provider Node, where the corrections to be made to .index-provider/config is described, it is only mentioned that the content of PeerID should be copied to the ProviderID property. However, it is also essential to ensure that the rest of the properties in the Reframe object is updated to match the example code. In fact, the only thing in the example code that should not be copied verbatim to the Reframe object is the content of the ProviderID property.
