Configuration doc changes / questions

In the 'configuration' section of readme.txt:

* Enable "Inline filter" in the input formats you intend to use. To do this, go
to Administer >> Input formats and click on one of the "Configure" links. For
instance, you can click on the "Configure" link for "Filtered HTML" and then
you will see a list of filters including "inline file filter". Turn that on
and click on "Save".

Change "Inline filter" and "inline file filter" to "Inline contents".

* Go to Administer >> Site configuration >> Inline and edit the maximum width
and height for inline images. If an image exceeds those dimensions, it will
be displayed as text link to download (like any other attachment than images).

Please note that this configuration setting no longer applies if the optional
ImageCache module is installed.

I don't see the 'Administer >> Site configuration >> Inline' option on my site. I'm not using ImageCache.

* Add to the CSS stylesheet you're using in your theme (usually style.css) the
following lines which you can tune to your needs. This style will be used by
the module to display images.

.inline {
float: left;
display: inline;
margin: 0 1em 1em 0;
padding: 4px 4px;
}

Is this still needed? I haven't added it (I'm using a Zen-based theme), but everything still looks ok.
