I have a tiny bit written about it here <http://inmysocks.tiddlyspot.com/#How%20to%20Add%20Fields%20to%20Tiddlers>, but you are asking for something really vague. If you have something more specific than I would be happy to help but for what you are asking the answer is just add fields at the bottom of the edit view of a tiddler and then reference them using text references <http://tiddlywiki.com/#TextReference>.
There isn't really any comprehensive guide to starting with tiddlywiki yet. Some are being worked on, but for the moment none exist. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
