||It has been suggested that HOWTO article be merged into this article. (Discuss) Proposed since February 2013.|
A how-to is an informal, often short, description of how to accomplish some specific task. A how-to is usually meant to help non-experts, may leave out details that are only important to experts, and may also be greatly simplified from an overall discussion of the topic. One of the earliest how-to books was published in 1569 by Thomas Wight and entitled, A booke of the arte and maner, how to plant and graffe all sortes of trees: With divers other new practise, by one of the Abbey of Saint Vincent in Fraunce by Leonard Mascall.
Modern examples 
In the modern era how-tos can range from brief directions to aid in performing a task one is unfamiliar with to full-length books, generally intended to assist or inspire life-changing methods and attitudes. They occur in the "self-help" genre, business books, and the hobby industry.
A similar concept is the [topic] For Dummies series of tutorials, as is the use of the suffix "101", based on academic numberings of entry-level courses, in how-to and introductory tutorial titles.
How-to manuals have existed in some form for as long as people have spoken to each other. Before writing, they took the form of instruction in oral tradition. The older generation taught the younger through proverbs and parables, and when languages became written, these were written down.
When writing was invented and people learned to read, people began writing down their oral teaching traditions. This was the birth of the how-to manual. Eventually, the genre broadened to include instructions for more than just common life skills. Authors like Plato developed books like The Republic, a how-to manual about forming the perfect society. Later, Ovid wrote the "Ars Amatoria," which describes in a mock-didactic form how to seduce women. The Renaissance saw a new birth of the how-to manual. While in medieval times, the focus was on survival rather than literature, the Renaissance allowed people to explore more topics, and texts like Machiavelli's The Prince developed. As time advanced, how-to manuals broadened to the form that we see commonly today: texts giving instructions for various pursuits, like drawing, painting, swimming, and other hobbies. Now, these manuals are both printed and on the internet, and are easily accessed by everyone.
Usage in the world of computers 
It is common practice to write the phrase as "HOWTO" in the Linux community. This may be for stylistic consistency with the related terminology FAQ and README. Another possible reason is that this makes it easier to find a how-to in search engines like Google as searching with the words "to" and "how" does not necessarily deliver relevant search results.
In the beginning, most how-tos on the Internet were the result of a complex process in which an author wrote a how-to for potential readers. After 2001, user added content played a more and more important role on the internet in a trend that is widely referred to as Web 2.0. This had a profound impact on the way in which how-tos are generated on the internet, as the readers and users were able to add to and improve the on-line content.

- As of 2009 A Google search for "How To" results in a comprehensive list of HowTo sites. It seems this has changed throughout the years. In the 1990's and early years of 2000, it was common for search engines to ignore these words, and even to notify the user that these words are too common for giving a comprehensive result. Currently, the Google features web page says: Google ignores common words and characters such as where, the, how, and other digits and letters that slow down your search without improving the results. If a common word is essential to getting the results you want, you can make sure we pay attention to it by putting a "+" sign in front of it."
- . A search on Google for "howto faq" or for "faq howto" results in FAQs with HowTo instructions in them, but never to a single HowTo page. This is probably due to the fact that FAQ pages are usually broader in scope, and therefore more commonly used.
