Sacred Steel (musical tradition) Wikipedia stub

YOu do not have to be a registered memer of Wikipedia to make edits but registration is free. If you do register, you can join any one of the various music projects that exist there or just skip around and edit what you like. If you need help with formatting, let me know via PM.

To make new sub headings you use this

==what you want heading to read==

That's about all you really need to know for basic editing. Citing sources is a bit more complicated. There are several ways to to do it. The easiest is:
[web-adddy of site_title of article]

I can then change the ref formula a little to make automatic lists of the sources.
