Example Input: [header] How to dye your hair with coffee [title] Brew some coffee. [step] Brew about 1-2 cups (240-470 ml) of organic coffee. The coffee should be organic, because non-organic coffees usually have added chemicals and preservatives. <sep> (A) For best results, make your own coffee by just boiling water for at least 30 minutes before you dye. [substeps] It's important to pour the brewed coffee into a shaker and bring to a boil. (B) [title] Reserve the coffee, if you don't already. [step] Coffee typically comes with an anti-aging coffee stain, which means it defroshes much faster in the summer than it does in the winter. (C) It is important to serve the coffee as soon as possible to ensure that it takes at least 24 hours to brew. If the coffee is sitting in your refrigerator, turn it cold to speed up the process. (D) Be sure to use a dark roast coffee or espresso. This will help make sure your hair will darken with the coffee.

Example Input: [header] How to substitute pornography [title] Find fun activities. [step] Instead of temporary pleasure that you may feel guilty about later, invest in your happiness. If you don't have any work to do, then start doing what gives you happiness (porn gives pleasure, not happiness). <sep> (A) Meetup.com provides fun and downloadable activities. [substeps] If you love reading, then find something reading. (B) Create activities that take your mind off the sugar and waste accumulated in the body. [substeps] For example, you might take your cat for walks every sunday morning, play charades, take a walk in your neighborhood, or watch a funny show on youtube. (C) Instead of spending time watching pornography as it is relaxing and educational, use it for fun and discovering how the world works. Take that step and visit your local library and check out reviews. (D) Find activities that take up a large chunk of time that will allow you to get out of the house or at least be occupied for a substantial amount of time. [substeps] Invest in some hobbies you find enjoyable, especially social hobbies that allow you to make friends and have fun.
