Dreads in steps

If I am going to do twist/rip dreads, what are my steps? Do I wash with non residue soap first? Do I need to dry it? And can I do part of it at one time then other parts of it later or does it need to be all at once? I asked below, but do you think me and a friend could do it, both of us having never done this before, but watched the vids on here?

yea its easy to do yea id wash 1st to remove conditionersid let it dry cause wet hair breaks eassier but also is easier to knot so if its slightly damp still thats finejust be gentler till dryand u can do it at different times but if u can do an all day thing and get it done u should
