- Instead of editing pages in a stupid web form, you can use vim and commit
- changes via svn. Or work disconnected using svk and push your changes out
- when you come online. Or use git to work in a distributed fashion all the

+## Supports many markup languages
- By default, pages in the wiki are written using the [[MarkDown]] format.

- by ikiwiki. Markdown understands text formatted as it would be in an email,
- and is quite smart about converting it to html. The only additional markup
- provided by ikiwiki on top of regular markdown is the [[WikiLink]] and

- unchanged by ikiwiki as it builds your wiki. So you can check in an image,
