people really make it sound harder than it really is, you can do it! It takes a month or more, so patience is required.
Will you be buying the liquid test kit? It isn't required but it is good to see exactly what you are dealing with in the water chemistry.
I have only cycled my original 5 gallon, after that it was easier to "seed" my other tanks with bacteria from the original tank which makes everything much faster.
If I were to do it all over again I would not hesitate to use a few snails to start the cycle. As soon as you get readings of 0 ammonia, 0 nitrite and just a little nitrate, you're good to go with fish.
I like this post about cycling:
