Dbt and spark how to use it

Hey everyone, i just started using dbt on my mac. I installed all the necessary prerequisites to make a simple project with dbt and spark.
when I run dbt init project1 in terminal a folder is generated with dbt-project.yml and the other folders. Is normal that profiles.yml is not generated should i created by myself?
my second question I want to make a basic example locally on my machine where I use pyspark and dbt.could you give me the necessary steps? from A to Z.
Thank you
