+#### Editing 
+The easiest way to edit a page on this wiki is to click on the edit button on the top of the page. New pages can be created using the "create" button.  The content of a page is written in "Markdown" syntax - which means it is mostly plain text with some symbols and annotations to add formatting. For more details on syntax see the [CommonMark](https://commonmark.org/help/) syntax guide.
