Some reasources require Krita to be closed and then opened before they appear also not all brushes have their own tags/catagories so some brushes may be in the “All untagged” catagory. If you have not added/imported any reasources (brushes for example) before, I highly recommend reading the manual for importing reasources here.
Some of the most popular brush bundles on the fourms are linked below. If the included brushes are not to your liking and would like to use what others have created, you can import or create your own bundle of brushes (which can then be shared with other Krita users). Any of the brushes can be copied and edited to how you want with the amount of settings that are assigned to each brush engine. I would start with the brushes that are already included with the program first. If there isn't click on it and then click 'activate' at the bottom. There should be a white line around Krita3DefaultResources.bundle. Go to Settings -> Manage Resource Libraries, and make sure the Krita 3 resource bundle is activated. Krita also has a pretty comprehensive brush editer (the hotkey for this menu is f5) The manual has a section dedicated to the brush editer which can be read here. Krita has two braid images for the brush tip, but you'll have to attach them to an existing brush yourself. Reguarding which brushes to use, this is a highly sugestive questions depending on what you create, your style and how you work.
