I did this for the first time last year.
Stick a stick or something in the ground and gently wind it around it when it's just starting out, if whatever you're using as a trellis doesn't go all the way down. Be gentle and don't worry if it doesn't latch on right away.
I let three shoots grow off each plant and prune the rest away. My trellis is pretty high, maybe 15-20 feet or so. My theory here is the fewer shoots you have, the faster and taller they will grow, but growing higher than your trellis doesn't help anything, so if I only had 6-10 feet to grow up I might try a few more shoots. All I can really say for sure is 3 worked nicely for me last year.
They like sun, plant it somewhere sunny.
Once they're going, I prune the bottom foot or two of leaves off. You're not going to harvest much down there anyway and it helps keep bugs off.
Watch for aphids (tiny white bugs) if you find them spray the underside of the leaves with a soapwater solution before they take over.
First year crops are notoriously low. So don't get discouraged if you don't end up with much or any in your first year.
That's all I've got after doing it for only one year myself. Lots of stuff out there on Google too.
For balcony growing, I'm not really sure. I know the plants have fairly extensive root systems, so they're generally ill-suited for being grown in pots. But it's probably possible, you'd just end up with a lower yield. I would also worry a little about the plant dying over the winter, but I don't know if that's justified. I don't really have any personal insight here, sorry.
