Review comment:
Maybe use the same example above from TDB? Copying that part with the timeout (quite sure it's the same syntax, there's another example in [the docs](https://jena.apache.org/documentation/fuseki2/fuseki-config-endpoint.html)).
Same for `unionDefaultGraph`. Maybe just leave it commented out.

Review comment:
Maybe make a reference somewhere in the docs that this one here, is one of the values from the reasoners listed in the next section?

+##### Possible reasoners:

+* **Generic Rule Reasoner**: `http://jena.hpl.hp.com/2003/GenericRuleReasoner`
+
+ The specific rule set and mode configuration can be set either be method calls to the created reasoner or though parameters in the configuration Model.
Review comment:
"can be set either be method"... by method?
"or though"... or through? (not a native speaker, so take it with a grain of salt)
