As pointed out in both the video and our last news on this topic, you'll gain skill points by exploring, doing quests and levelling. You can then spend those points in several skill lines in eight major categories: race, class, weapons, armors, guilds, PvP, world and tradeskilling. Those skills can be active or passive. Each level, you'll also gain a point that can be used in one of the three attributes (health, magicka, or stamina).
The questions asked gave answers on several points, as seen below.
