The formatting rules are based on YukiWiki.
silk web is a Web-based hypertext tool with an emphasis on linking. Creating links between nodes in silk requires just one mouse click -- you never need to manually type node identifiers (e.g. URLs or CamelCase node titles). It can also track links to the external Web, and you can manage these links with the same one-click functionality. It works well for organizing ideas and the connections between them (it was designed for personal note-taking), though it can also function as a public space for collaboration, much like a Wiki (like a Wiki with smooth linking).
