Notes need to be numbered

[Nat Sakimura]

Currently, they go like

NOTE: Some text goes in here.

NOTE: Some other text goes in here.

OR

NOTE:

Some text goes in here

NOTE:

Yet another text goes in here.

They need to be Numbered in the following style:

NOTE 1: Some text goes in here.

NOTE 2: Some other text goes in here.

so that they can be referenced.
