Summarize the following:
Although the functional reason for documenting software is to help users understand how to use the application, there are other reasons as well, such as assisting in marketing the software, enhancing the company image, and most notably, reducing technical support costs. In some cases, documentation is necessary to comply with certain regulations or other legal requirements. In no case, however, should software documentation substitute for poor interface design. If an application screen requires reams of documentation to explain it, better to change the screen design to something more intuitive. In most cases, software users have little knowledge of computers outside of the tasks the applications they use enable them to do. There are several ways to determine how to address their needs with your documentation. Look at the job titles your prospective users hold. A system administrator is likely expert with a number of software applications, while a data entry clerk is more likely to know only the application he or she currently uses to enter data. Look at the users themselves. Although job titles generally indicate what people do, there can be considerable variation in how certain titles are used within a given organization. By interviewing prospective users, you can get a feel for whether your impressions of what their job title indicates are accurate or not. Look at existing documentation. Documentation for previous versions of software, as well as functional specifications, provide some indication as to what the user will need to know to use the program. Keep in mind, however, that end users are not as interested in how the program works as they are in what it can do for them. Identify the tasks needed to do the job, and what tasks need to be done before those tasks can be done. Software documentation can be structured in 1 of 2 formats, the reference manual and the user guide. Sometimes, a combination of formats is the best approach. A reference manual format is devoted to explaining the individual features of a software application (button, tab, field, and dialog box) and how they work. Many help files are written in this format, particularly context-sensitive help that displays a relevant topic whenever a user clicks the Help button on a particular screen. A user guide format explains how to use the software to perform a particular task. User guides are often formatted as printed guides or PDFs, although some help files include topics on how to perform particular tasks. (These help topics are usually not context-sensitive, although they may be hyperlinked to from topics that are.) User guides often take the form of tutorials, with a summary of the tasks to be performed in the introduction and instructions given in numbered steps. Software documentation for end users can take 1 or several of many forms: printed manuals, PDF documents, help files, or online help. Each form is designed to show the user how to use each of the program's functions, whether in the form of a walkthrough or a tutorial; in the case of help files and online help, this may include demonstration videos as well as text and still graphics. Help files and online help should be indexed and keyword-searchable to allow users to quickly find the information they're looking for. Although help file authoring tools can generate indexes automatically, it is often better to create the index manually, using terms users are likely to search for. Printed or PDF user manuals can be written with a word-processing program like Word or a sophisticated text editor like FrameMaker, depending on their length and complexity. Help files can be written with a help authoring tool like RoboHelp, Help and Manual, Doc-To-Help, Flare, HelpLogix, or HelpServer.

summary: Determine the business reasons for your documentation. Understand the audience you're writing the documentation for. Determine the appropriate format(s) for the documentation. Decide what form(s) the documentation should take. Choose the appropriate documentation tool.

Summarize the following:
The first extension that you will measure and apply is the piece that goes around the perimeter. Take your extensions out of the package, and open one weft so that all the hair is exposed. Starting at the beginning of your perimeter braid, hold the extension in place, and wrap it around your head. Hold it to the perimeter braid the entire time to make sure it is the right length. When you get to the end of the perimeter braid on the other side, measure a little extra hair, and then trim it to fit. Place this piece of perimeter-extension off to the side, so that you don't misplace it or confuse it for another section of hair. You're going to be working with a long strip of extension, but you won't be able to use all the necessary thread in a single shot. Cut a piece of your weave thread that is 56 feet (1.51.8m) long, and use the same process as you did for your wig cap by threading it through the needle, matching the ends, and tying them together in a knot. Cut off any excess string. Work around your head, using the exact same process of sewing your weave to your cap/braids as you have been. Remember to always double knot over a fold or the beginning of a weft, to properly secure it. When you have finished filling in your head, trim off any excess that might hang over the front. When you've sewn on extensions to all the small braids along your part, you should be left with a space in the back that is still open. To fill this in, you'll have to prepare a special piece of your weave. Measure the space that you have to fill, and cut a piece of your weave that is twice that length. Start with your regular double knot at the end, and then roll the weave in to create a small circle. Create an additional knot by looping around the two layered sections of weft, and pulling it tight. Continue rolling and knotting the extension until you have finished the whole piece. When you tie the last knot, pull the needle through all of the layered wefts to secure them together. Cut the excess string off when you're finished tying it. Turn your closure piece upside down so that the weft is facing the ground, and the hair is upwards. Begin flattening the hair so that it falls down over the top of the rolled up weft. Because of the roll that you created, the hair should fall evenly around it, hiding the weft and your sewing. It may be helpful to use a flat iron on the hair to get it to cooperate with what you're trying to get it to do. Secure the ends of the hair with a small elastic to making sewing it to your scalp much easier. Turn your closure piece back over so that the weft is exposed, and insert your needle and thread through it to tie your regular double knot. Bring your closure to your scalp, and place it where you want it to go. Insert your needle through a braid or a piece of weft from another extension nearby on your scalp, and pull it tight to create your regular knot. Continue doing this in a circular movement around your closure piece, until you've gotten back to the beginning. Cut off the excess string, remove the elastic from your hair, and you're done! Adjust the strands of your closure piece to cover up any weft that may be visible.

summary: Measure your extension-hair for the perimeter braid. Prepare your thread. Finish filling in your head. Create your closure for the back of your part. Adjust your closure piece. Sew your closure to your head.

Do this at least twice a day, for at least two minutes each session. Invest in a portable toothbrush and toothpaste if you frequently consume garlic or onion. Brushing on its own only cleans just over half of the surface of your teeth, and thus it is important to floss, as well. You should ideally be doing this after every meal. An antibacterial mouthwash containing chlorhexidine, hydrogen peroxide, or cetylpyridinium chloride will help to prevent bad breath. Many brands of mouthwash contain alcohol, which can dry out your mouth (a cause of bad breath), so avoid these brands if possible. The filaments on your tongue trap tiny particles and bacteria; the major proportion of odor-producing bacteria are found on the tongue. Thus, when you brush your teeth, also clean your tongue with a tongue cleaner or toothbrush. Using an irrigator or water pick cleans food particles from around and under your gums and between your teeth. If you aren't getting foods out through the methods listed above, they are rotting and festering in your mouth; a water pick will help to remove stubborn food particles.
summary: Brush your teeth. Floss. Use mouthwash. Use a tongue cleaner. Use a water pick.
