E-Learning Portal: How to edit a page in ModX

This is the main page for which I did my work in ModX. Keeping it quite simple, you can manage many pages of content working with just the template and content pages. Because the template is the only page for which I am adding styles, I found it more convenient to keep the CSS styles embedded in the page. Poor practice I know, but convenient.
How to edit content pages:
1. To edit a page, click on a name on the left hand menu.
2. The page properties show up in the main work area.
3. Click the EDIT button, also get in the habit of selecting the Continue Editing radio button.
4. You will only be able to code in HTML, no WYSIWYG yet.
How to edit template pages:
1. Click on Resources in the tab menu on top.
2. Click on Manage Resources in the second level of the top menu bar.
3. It should now look like the above graphic. Click on EDIT.
3. Click the EDIT button, also get in the habit of selecting the Continue Editing radio button.
