Hi @Ali1Abbas
Congratulation on the new task 
. I hope our documentation will be useful during that task execution.
For development without docker you can check the binary installation page for your OS in particular here.
If you have multiple unrelated questions, I suggest that you create a post per question, such that other users will find them easily when searching for similar things.
Best,
