Documentation for the Sling Resource Editor

[Sandro Boehme]

Hi,

I would like to create online documentation for the Sling Resource 
Editor to get more users/contributors/committers for it.

Now I wonder if it's practical (and allowed for me) to add the docu at 
the public Sling website even though the decommissioning of the CMS is 
proposed.

Or if it's better to use the Confluence wiki. Can somebody tell me how 
to get write access if I should use the latter?

Best,

Sandro
