Adding setup steps

Discovered there are steps required that are not docuemnted regarding the schema.

This adds those steps in.


The console is referenced below (the crawl command includes the console), so I think we can leave the second sentence here off.

Also `cqlsh` is mistyped. Can you change that line to:
```
cqlsh -f schema.txt # optionally change replication information for the keyspace in schema.txt before loading it
```
