Categories should be added to the bottom of a tip.
Each tip is in one or more categories.
Each category is in a parent category.
For example, there may be categories:
- VimTip
- Usage
- Folding
- Usage
If a tip concerns folding, it should be in the Folding category (which has the Usage category as its parent). That will help people find information on folding.
This page lists the tips in the folding category.
This page lists all categories.
There is also a category tree (requires javascript).
You may edit a tip on folding and find the wikitext:
[[Category:Usage]]
That means that the tip is in the Usage category (which will be shown at the bottom of the tip page). In that case, you should change the category by replacing "Usage" with "Folding", so it reads:
[[Category:Folding]]
If the tip is not in the Usage category, you would simply add the above line to the tip (at the bottom).
