Template:Reff/doc

Both parameters are bare numbers. A space should always be used after this template otherwise it is pretty illegible/ugly.
 * 1) the id, i.e. controls the note line that the ref link goes to. This can be the same as another if the ref is pointing to the same note.
 * 2) the number that shows up next to the note. This is an optional parameter that only needs to be used if more than one reference is pointing to the same note. Each different note should go from 1 again.

Examples: Text #1 Text #2 Text #3 This is my note for #1 This is my note for #2 and #3

from typing Text #1 Text #2 Text #3 This is my note for #1 This is my note for #2 and #3
