For the first, ikiwiki automatically rebuilds as needed when a template is
changes.
I don't entirely understand what the second is trying to say.
* Start from an existing [[CSS file|css]], see also the [[css market]] for examples
* You can override the [[templates]] files by dropping them in a `templates` subdirectory
* Try to stick with modifying the CSS however, maintaining custom templates is harder
- * If you *do* override a template, note that you will need to rebuild the wiki for it to be applied...
- * ...it may therefore be preferable to load the template directly in your browser to develop it
