Twinic is still in a pretty early stage. Most of the help sections need to be written still so here is a quick link to a Textile Reference. Textile is the markup language we use around Twinic. It can help you to add more stuff to your notes like emphasized text, complex URL’s or lists. An even shorter introduction can be found on Wikipedia.

PS: for your convenience, as of today, if you type an URL in your text boxes, Twinic automatically converts this into a real link!
