Adding setup steps

Discovered there are steps required that are not docuemnted regarding the schema.

This adds those steps in
adjusting caching rules

When trying to get up and running the repvious caching rules caused errors:
Invalid value for property 'caching'. It should be a string

After trying various alternatives al messages seemsed to suggest that the only valid
types were ALL, KEYS_ONLY, ROWS_ONLY, NONE. Given what was there it looked like NONE
was the desired option.

README.
