Description

The Upgrading NiFi document on the wiki refers to 0.4.0 as the "new version" of NiFi. It should be updated with the following considerations:

• 1.x branch is now current, which means significant changes have occurred, including ZMC, ZK, and multi-tenant authorization
• The document has numerous spelling and grammatical errors, some of which seriously affect comprehension (e.g. "static files from the conf directory will not be located" should be "static files from the conf directory will now be located")
• The document does not explicitly explain how the default location of various resources is modified until the end of the file where an example nifi.properties is provided

I think reviewing and updating this document with a new set of eyes will greatly improve it and make it a relevant (and hopefully more long-lived) resource for users.
