If you are referring to the slides, they are done by sliding your finger up or down. If you are sliding in first position you may start the note slightly below or over and slide to the correct tone. Sometimes you'll want a fast not so blunt slide and sometimes you'll want to emphasize it.
If practical you can slide up to a position.
This girl is petting the notes a lot too. Applying and releasing pressure to have smooth starts and changes to the notes.
Very ambitious question for a beginner.
