[Orgmode] Indentation of text below headlines

[onguarde -]

Peace all!

I'm trying to make text below headlines indented as per the example quoted below.

Indentation of text below headlines
You may indent text below each headline to make the left boundary line up
with the headline, like

          *** 3rd level
              more text, now indented
A good way to get this indentation is by hand, and Org supports this with
paragraph filling, line wrapping, and structure editing1 preserving or adapting the
indentation as appropriate.  A different approach would be to have a way to
automatically indent lines according to outline structure by adding overlays
or text properties.  But I have not yet found a robust and efficient way to
do this in large files

[1] See also the
variable org-adapt-indentation.

If the variable `org-adapt-indentation' is non-nil, the entire text is
also indented so that it starts in the same column as the headline
\(i.e. after the stars).

.emacs config file
;(setf org-adapt-indentation nil)
(setf org-adapt-indentation t)

I tried setting it up it .emacs like so but it doesn't seem to work no matter which I comment.

Am I missing something??
