Hello @nasr.alkadry85
That’s fine, but if you don’t know anything about dynamo, try a little research, here on the forum, that’s how I started and go through the primer and learn section, there’s lots of material on youtube too…I like Gavin’s videos, and Jacob and Sol’s office hour…and otherwise just practice as much as you can…step by step…and I can say you’ll never be finished, there’s always something new we can learn and that’s cool 
and btw thats a great advise you get…dynamo is very powerfull
