I would like to see a more clear/simple explanation. Too much words, the folders contents are not clear for me. Please help

I already have the necessary files: mymap.pk3, mymap.jpg and mymap.vdf.
How do I fold them?

OK, my map is uploaded :))))
Now i want to play it with my friends. What I need to do? Someone told me something about PORTS...what does that means?

Network devices have ports. Think of it like gates in airports. You need to make sure that the information going towards your IP can reach your QL server after it hits your router. You have to tell your router to redirect anything reached its port X towards the port X of the computer hosting the server. That's called port forwarding and there isn't a single universal tutorial for that. You should try searching on the internet for your own router model.
Read the linux dedicated server guide for more information on which ports need to be opened. I take it you're only gonna use a listen server but many things from this guide still apply.

Hi FlashSoul
I`ve been around reading information about adding ports to my router and all that made me feel like a web retarded. I will try to understand how to make it and I swear i will play my maps with my friends. Ty
