Editing KSI Wiki:Beginners Guide (section)

=== Editing an Article ===
You can edit an article when you have Editor access by visiting a page and clicking "Edit" at the top of the toolbar. The editor screen is similar to the Page Creation screen in that you have an editor window, but the options that appear below the editor window are slightly different. 

First, you have a Summary box. It is recommended to put a brief summary of what you are editing and why it was changed within this box so that if changes need to be reverted back to or reviewed at a later time, editors can see exactly why something was changed.

Below that, you will have two checkboxes. By checking "Watch this page", the page will be added to your personal watch list where you will be able to refer back to it at a later time. By checking "This is a minor edit", the edit will be marked differently in the page summary, as well as the edit will not count towards your total editing count. We use minor edits for things like punctuation & grammar updates, or altering file links. Think of it as things that don't necessary alter the core contents of the page.
