\label{Docs_Overview}
A LON-CAPA course is managed through
the \textbf{Course Editor} screen which can be accessed in a number of ways.

\begin{itemize} 
\item Selecting \textbf{Course Editor} in the Inline Menu
\item Selecting \includegraphics[width=0.03\paperwidth]{docs} 
\textbf{Edit course contents} from the Main Menu.
\item Clicking the \includegraphics[width=0.03\paperwidth]{docs} icon in the Tools at the top of
the Course Contents screen.  
\item Clicking \includegraphics[width=0.015\paperwidth]{editmap} to the right of a folder name 
on the Course Contents screen. (Editor will open that specific folder). 
\item Clicking \includegraphics[width=0.015\paperwidth]{docs} in the Functions menu when viewing 
content in the course. (Editor will open that specific folder).
\end{itemize}
The Course Editor screen allows you to create new resources, upload resources or import 
LON-CAPA resources from the LON-CAPA network.  The screen also allows resources to be 
rearranged within the course.

The Course Editor contains three tabs: 
\begin{enumerate}
\item Main Content Editor
\item Supplemental Content Editor
\item Content Utilities
\end{enumerate}

\textbf{Main Content Editor} tab is used to manage the primary content of the course. 
Content within this area can:
\begin{itemize} 
\item Have parameters set (including dates controlling availability)
\item Can be incorporated in PDFs for printing, created by LON-CAPA's print utility
\item Can be a part of sub-folders for which different students may see a subset of
      contents picked from a pool, and/or contents displayed in a different order.
\item Be organized within a hierarchical arrangement of folders and sub folders.
\item Can originate in a variety of ways including import from the shared content pool.
\end{itemize}

Within the course, students use the navigation 
controls to move through the Main Content. \textbf{Main Content}\index{main content} is listed on
the \textbf{Contents} screen. Main Content was added to
LON-CAPA in 2003 (version 1.0), so pre-2003 courses (as well as courses deliberately created in
the old style) will not have Main Content. The Main Content was called 
Main Course Documents\index{main content} in versions 1.0 through 2.10.

\textbf{Supplemental Content Editor} tab is used to manage supplemental content in the course.
Content within this area is restricted to uploaded files, a syllabus page, a web page created using
the HTML editor, or a web page on an external server retrived from a remote site, but displayed within 
the LON-CAPA interface. A hierarchical arrangement of folders and sub folders can be created. 
Students access supplemental content documents by selecting the 
\textbf{Supplemental Content} tab while viewing the \textbf{Course Content}. Supplemental Content
is particularly useful for auxiliary files that may not be directly viewable
or usable in a browser, such as PowerPoint presentations or Word documents --
some of which may require a viewer to be installed on a student's computer.

NOTE: Although the Course Editor provides instructors with the ability to import content
from the shared content pool, or to copy content from other courses, as well as personalize 
courses with their own syllabi or information pages,  for the ultimate power
in creating reusable content, you will want to become a content \textbf{Author}.  This is
especially true if you plan to create your own assignments.  The ``simple problem'' templates
available to create assessment items directly with a course, provide a much restricted set of
components compared to those available when constructing assessment items as an author.

Policies and methods for creation of \textbf{Author} roles vary depending on user status and domain. If you are a course instructor, and you do not have an authoring role, and you do not see a ``Request author role'' link on your Roles page, make a request through the ``Ask Helpdesk'' link available on the ``Help'' page.

the LON-CAPA Author's Manual available online at \texttt{http://help.lon-capa.org} .
