Moin has provided instructions for common usage. Try creating a wiki using the default values within the instructions. Your wiki would then be stored where ours is, and named mywiki ... but you can change that place, and this name, AFTER you have a working wiki. The default values have been chosen carefully to work for most people on most platforms, or at least be a good start.
- First follow the instructions
- Do not change any configuration option unless you must.
- Play with a working wiki before you try to customize it.
