I have made a full copy of Tiddlywiki.com (based on TW519) with lot of additional tags for "newbies".
I added a "structured" Quickref overview Tiddler to access all the concerned tags in context of a TiddlyWiki.
These tags can be used and as a starting point to jump to all related Tiddlers.
I also added a Tiddler explaining the very basic things you need to know about TiddlyWiki and Tiddlers. Includiing a little diagram (~DFD) how the TiddlyWiki is modified in memory.

To accomplish the above I applied many many many ... tags to all the non-system Tiddlers.
New tags I added are for instance : images, media, searching, saving, browser, Links, node.js and many more...
It is not yet polished (tags do not always start with an upper case, see also note below ) but it will give you a good idea of the added functionality for "newbies".
Let me know what you think.
Please note this is work Work in progress !
Tiddlywiki also uses tags to create lists of similar Tiddlers. I was not always aware
of this. This sometimes resulted in tag conflicts when I tried to re-use an existing tag
(e.g. Resources became recursive).
