 Contributing to the Wiki is now easier than it ever has been. Using the Atom editor will give you an easy to use interface that is cross-platform, has code completion, syntax highlighting, instant AsciiDoctor page previewing, with an integrated GitHub client. The only thing it doesn't do is write the page for you.
 
 == Atom Editor Setup
+
+.Prerequisites
+.  Have a link:https://github.com/[GitHub account].
+.  Are a Wiki project member.
+
+If you are not a member, you fork the repository into your GitHub account and issue "`Pull`" requests to the Wiki repository from there.
+
+To fork the Wiki repository into your GitHub Account:
+
+.  Navigate to link:https://github.com/jMonkeyEngine/wiki[https://github.com/jMonkeyEngine/wiki].
+.  In the menu at the top of the page, select the icon:code-fork[]*Fork* button.
+
+== Downloading the Sources

 .  Download and install the Atom editor - https://atom.io/
 .  After installation is complete, you can customize the editor by selecting the `Choose A Theme` panel followed by the btn:[Theme Picker] button.
 .  Once you are satisfied with the customization of the editor, you will need to add several packages to make Atom AsciiDoctor compatible. Package installation is painless.
 **  From the `Install A Package` panel, select the btn:[Open Installer] button, or select `menu:Packages[Settings View>Install Packages/Themes]` from the file header.
 **  Enter "`asciidoc`" in the search box and press the btn:[Packages] button.
-** Add these packages:

-*language-asciidoc* +
-*asciidoc-preview* +
-*autocomplete-asciidoc*  +

-**  Select btn:[GitHub: Clone].

+IMPORTANT: Use the +++<abbr title="Uniform Resource Locator">URL</abbr>+++ to your repository fork and clone your fork if a non-member.
+
+..  When you're ready, press the btn:[Clone] button.

 The clone will take some time due to the size of the Wiki. Once cloned, a new `Project` tab will open on the left, and the `Git` and `GitHub Preview` tabs will open to the right. If they don't, you can open the Git tab using kbd:[ctrl]+kbd:[shift]+kbd:[9]  and the GitHub Preview tab using kbd:[ctrl]+kbd:[shift]+kbd:[8]. Alternatively, you can navigate the `menu:Packages[GitHub]` menu. You will also notice in the lower right corner, on the `Status Bar`, you now have your GitHub control.
 
 All Wiki documents live in the `asciidoc` folder, images in the `images` folder, and resources for your documents in the `resources` folder. Select an appropriate folder under each to store your new document, image or resource.
 
 Before you can commit any changes to the Wiki, you must configure at least the user.email and user.name variables for Git. You can do this via Git Bash, or manually, by following these instructions.
