I have no clue what I’m doing, but I’m ready to start. Help?

Hi everyone! I'm here asking for guidance and suggestions.

This is my first ever Reddit post, so please bear with me.

I live in Italy, and I've finally moved into a house where l'm allowed to have a garden! I've only ever grown indoor plants before, but they made me so happy that I really want to grow a real vegetable garden now that spring is almost here.

I'm currently traveling for work, so I drew this poorly drawn map from memory on a bumpy train. I won't be home to fact check myself for a while, so everything is scuffed, proportions are likely off, I might be forgetting important details, and the only accurate info I'm sure about is the compass I left in the top right corner, but it should still give an idea of the general layout of the area, and I'd like to gain knowledge and be ready before I return home.

Now that I can, I would like to ask someone more experienced than me what to do with all this. What vegetables are fit for the Italian climate? I really like both vegetables and herbs (this last one is what I had indoor), where should I plant what? Any immediate first steps I should take once I get back home?

I hope that I left enough details in the drawing to explain the situation, but I will answer pretty much any question to provide more context if needed.

Thank you so much to anyone who takes the time to help a nervous beginner!
