Enochian is the language of the angels (according to John Dee and Edward Kelley). Enochian magick is the name of the part of magick that deals with the summoning and commanding of spirits, demons and angels (it's also referred to as goetia). Goetic sigils are sigils of the 72 goetia spirits (the [lesser] key of Solomon). Basically the sigils are the "names" of the demon or angel you are trying to summon. There's a lot more you need to know and do to summon these spirits but I won't disclose that.
You can't really teach those type of things online, my best advice to you is to master the basic principles of magic (you're going to need them). Then move on and start practicing deep meditation, opening yourself up (becoming more sensitive to energy, opening your third eye, etc). It helps to learn how to draw more skillfully, develop your rhetorical skills, learn how to control fear and anxiety, know a couple of potent protection spells and to write legibly. Then you can do tons of research on summoning (what to do and what not to do), how to summon properly and banish properly, demonology, goetia, lesser key of Solomon, sigils, and different ways in which you can contact the spirit. Yes, I know it's a long list but enochian magic is the most advanced and the most intense magic there is, not for the weak minded. If you have any questions along the way you can message me anytime.
