A tutorial or an exercise follows the same structure as a Feature page with the extension of a requirements/precondition section (defining what skills and resources are needed) below the summary and an indicator for the difficulty. Further should the summary list the features that are explained in this tutorial.

• Make clear what version of GroIMP is used and what plugins are needed (if they are not by default installed in that version)
• If the tutorial works with a specific model or resources these should be provided.
• Expected knowledge + reference to where to find

We know that it is very difficult to rate the difficulty of a tutorial but it makes usage of the wiki much easier. The rating in the how hard icon goes from 0(very easy) to 5(very hard). To add this use either the code {{howhard>2}} or the button in the editors menu.

If you create an exercise you might want to hide the solution, this can be done by using the <hidden> ...</hidden> tag.

For example:

What it the best software ever:
 
 
<hidden solution>
GroIMP 8-)
