Submitting error in documentation

Lesson 14: Controller Actions/DataObjects as Pages

Template code under " Rendering a DataObject as a page" section has a typo.

<div class="main col-sm-8">
    <% with $Region %>
        <div class="blog-main-image">
            $Photo.SetWidth(750)
        </div>
        $Description
    <% end_with %>
</div>
$Photo.SetWidth(750)

should be changed to
$Photo.ScaleWidth(750)

Also, is there a better place to submit documentation changes?

In the lesson page you mention there is that big button named Code repository that links to a GitHub repository. I think a pull request there would be more appropriate, although TBH the activity there seems quite low.
