Incorrect statement removed as per request by functional consultant in ticket #691426. Statement sets incorrect expectation. Also, minor rewording to correct English and improve clarity.
Removed the sentence from line 39:
**Don't be afraid of messing up the data**,
it's very easy to duplicate your database, clean it or start a new one.
Reason: It is possible to create records that are difficult to reverse, such as
accounting entries and delivery records.
RSH was consulted and approved the change.
Closes#149
