When you have mastered those, you can look into the dedicated introduction pages for functionality in the User Manual, read through the overarching concepts behind (digital) painting in the General Concepts section, or just search the Reference Manual for what a specific button does.

If you are new to digital art, just start with Installation, which deals with installing Krita, and continue on to Starting Krita, which helps with making a new document and saving it, Basic Concepts, in which we’ll try to quickly cover the big categories of Krita’s functionality, and finally, Navigation, which helps you find basic usage help, such as panning, zooming and rotating. I guess you would like to see painting tools working as vectors. There you can draw and edit Bezier curves and preset shapes like circles which are freely scalable like in Inkscape or Illustrator. To draw it you must insert a vector layer. If you are familiar with digital painting, we recommend checking out the Introduction Coming From Other Software category, which contains guides that will help you get familiar with Krita by comparing its functions to other software. Many raster image editing tasks go well, too. Welcome to the Krita Manual! In this section, we’ll try to get you up to speed.
