The witlesses will give you a self serving answer. First, you must study the Bible--and it has to be with the aid of one of their pieces of littera-trash, preferably the current one (the Bible Washtowel Teach book is it as of this posting). You will be required to set aside an hour a week, preferably twice a week, to study this book. Of course, you are expected to be prepared when they show up.
After a few weeks, you will start being required to give up the things that mean the most to you. At first, it will not be too bad--they usually start with the illegal drugs, spiritism, and the idols from other religions. At such point, they will also make a point to warn you that any information that seems to be against the religion is from Satan, and that you are wise to limit exposure to family members that do not subscribe to your new religion so they cannot sway you away from the "truth".
Next, you are invited to the Kingdumb Hell to go to the boasting sessions. Sunday is most popular as a starting point, since most people do church then anyways. Once you start going to the Sunday boasting sessions, they will start hounding you to arrange work schedules so you can go to the Tuesday or Thursday boasting sessions as well (it used to be both, but as of the beginning of 2009, they condensed it to one). Which will depend on whether your congregation has its boasting session on Tuesday or Thursday. They will want you to join the Theocraptic Misery "School(??)", including cleaning up your life of anything that blatantly contradicts the washtowel teachings. Usually, you will have had to cut ties to other religions, legalize or terminate your relationship with significant others, quit smoking if you smoke, and otherwise live a "clean" life. Pedophilia, however, is accepted--not officially, but as a matter of practice.
After a while of this, you will be required to give up other things that might "stumble" others. This includes a good chunk of your music and video library (not just the porn and very filthy music this time--anything that is even a little suggestive is "bad" this time, since others might be stumbled. If you do not, they will continually hound you and threaten that your salvation might be in jeopardy unless you comply. If you are in college, you will be asked to drop out (indirectly, of course). If you have children in college, you might also be asked to cut off funding or otherwise get them to drop out--of course, making it seem as if they made the decision). Everything about your life will now be analyzed, and whatever might stumble others is severely criticized.
Next comes field circus. You will be asked to go out in field circus "as much as you possibly can", to get a sense of what it is like and how to do it. You will have a partner that has experience, often your study conductor at first. This is supposed to be the hallmark of salvation, and of the religion.
Once you have field circus going, you will be asked to get baptized. This also is necessary, since it commits you to the organization in full. Once you take that step, you now have to remain active and faithful in order to get "salvation". Break any of the rules, fail to do field circus, or question anything the Filthful and Disgraceful Slavebugger puts out, or even show that they are blatantly wrong (with proof right from their own Bible that they are wrong), and your salvation is threatened. You must remain faithful like that until you die, or until Armageddon comes (which is supposed to be any day now, for the past 130 years).
And even then, you only may be concealed (Zephaniah 2:2-3).
