Every good demonologist knows that for true power in their field, one must be patient enough to learn the correct rituals and rites. Of course, there are certain steps used in building these ceremonies that must be followed in order to succeed. Following you can find the necessary steps to perform demonology rituals and rites correctly:

• Step 1: Research and Gathering
  All rituals and rites, as well as demonology itself, begins in one place: research. Always research the demon you may be summoning, the effects of a rite, or if you're creating one of your own, research what will fit into each aspect. Memorize incantations, gather ingredients, and research everything you'll need. Once you've done all of the research and gathered all the needed materials, it's time for step two.

• Step 2: Preparation
  It is always reccomended to begin preparing for a ritual or rite at least a day before you perform it. Make sure you have a proper spot, have things arranged correctly (if using body parts, it's probably best to get these fresh, but be sure you know where you can get them in advance), and are ready to begin. Why begin doing this so early? Because one mishap could mean anything from a little burn to your total destruction.
  
  You also should consider if you have to cast protection spells before the final ceremony so that you won't end up as your own victim of the horrors you plan to summon.

• Step 3: The Ceremony
  The ceremony is the culmination of the previous steps. Everything is researched, gathered, and set, now just to dive right in. Of course, the ceremonies themselves are also divided up:
  
  Part I: Markings
  Sometimes a ritual for summoning a demon will require markings with chalk or ash. Outlining a space for the summoning, drawing a picture of the demon, or maybe a symbol of power.
  
  In rites, such as the ones used by powerful demonologists to change parts of themselves, that part must be marked in certain ways also. If they want to have the eyes of a demon known for its incredible abilities when it comes to sight, then marks might be made around the eyes indicating them as the part being changed.
  
  Part II: Incantations
  This is not always used, but it's a good idea to discuss it anyway. Here you would recite any incantation or mantra which you learned for this ceremony when you researched it. Be very careful when it comes to wording, pronunciation, and speed. You must always get incantations exactly right or else they simply won't work or produce unwanted results. This is why most choose to leave incantations out when creating new rites or rituals. But make no mistake, they are a difficult tool, but also a very powerful one.
  
  Part III: Reagents
  At this point is when the ingredients become important, if any are used. Mix them together, move them into place, or do whatever is called for. Usually, when it comes to mixing, it is done during an incantation, giving the mixture more power. If your reagents are something that must be waved or in a certain place for the ceremony, then this must be done now.
  
  Part IV: Invoking
  Even if all rituals and rites don't use incantations or markings or reagents, they all have at least one thing in common. This point is when an invoking word is spoken and the power is brought out of them. This ends incantations, mixings or movings of reagents, and gives markings the boost they need to work. This is the end of your part in the ceremony and if you did it right, then the desired effect should have been achieved.
  
  Step IV: The Aftermath
  This is the moment of truth. Right after the ceremony you will know if you succeeded or failed. A demon will arise, your body will change, the thing you were trying to do will happen. Or you will be hurt, killed, maimed, sucked into the Netherworlds, any number of nasty things. Congratulations or good-Bye, what you set out to do is done. Please note that even if you manage to summon a demon, it is still not guaranteed that you in fact can control it. It can happen that if you haven't cast appropriate protection spells in advance the summoned being will turn against its summoner. Certain kinds of demons also require constant attention as they may get out of control once the magic power which is holding them in this world diminishes.
