Guides tell you how to stay safe. They also show how to put things together. You can learn how to fix a problem too.
Some guides are very big. They might have a small guide for quick starts. 
Old things had guides too. An old Greek machine had words on it. These words told people how to use it.
Guides make new things easier to use. They help you learn fast.

Guides have many parts. They tell you how to stay safe. They show how to put things together. This is called assembly. They also show how to set things up. Some guides help you fix a problem. This is called troubleshooting. 
Guides can be very big. Some people use a quickstart guide. This is a small guide for fast starts. Car manuals are often large. They explain how to use controls. They also list how to keep the car running well.
People have used guides for a long time. An old Greek machine had text on it.

Guides work by giving you information in steps. They often start with safety instructions to keep you from getting hurt. Some guides show assembly, which is how you put pieces together. They also cover installation, which means putting a product in place for use. You might find setup steps to get a device ready. There are also instructions for normal use and programming. 
People have used guides for a very long time. One famous example is the Antikythera Mechanism. 
There are many different types of manuals today. Some computer guides are on a CD-ROM to save money. Other companies provide instructional videos on a DVD. Many businesses now offer free PDF copies on their websites. Car manuals are often quite large because of many safety warnings. They tell you about fuel capacity and how to use controls. Some cars even use artificial intelligence to answer your questions.
Guides connect to many things you see every day. You might see a quickstart guide for a fast start. Some software has different guides for different groups of people. For example, Autodesk Topobase 2010 has guides for users and developers. You can even find guides for things that are not machines. People write instructional books about pets or even businesses. Even the term "owner's manual" is used as a way to describe these books.
A user guide, also called an owner's manual or instruction manual, is a document designed to help people use a specific product, service, or application. 

Manuals function by providing structured information through several key categories of instruction. Safety instructions are often very extensive because companies must provide warnings to prevent injury or damage to the product. Assembly instructions guide users through putting together products that arrive in separate pieces for easier shipping. Installation instructions explain how to put a product in place so it is ready for use. 
There are distinct types of technical documents based on their specific goals. An installation manual is a specialized document that focuses solely on the act of installation. This is the process of putting a product in place so it can be used. While an installation manual can be a separate document, it is often integrated into a larger owner's manual. The content of these instructions depends on the nature of the product and the needs of the user. For example, the European Machinery Directive requires that manuals for machines include specific details. These details must cover assembly, installation, and connecting instructions, including drawings and the means of attachment. 
Instructional documentation has a long and fascinating history. User guides are not a modern invention; they have been found with ancient devices. One famous example is the Antikythera Mechanism, a 2,000-year-old Greek analogue computer. 
In the early days of computing, mainframe documentation was very different from today. Before Unix, documentation for systems like GCOS consisted of printed pages kept in large steel binders. These binders were often bolted to tables or counters in offices so staff could access them. These systems allowed for modular updates, meaning users could replace pages or add new information easily. Today, most software manuals for PCs are book-like documents that can be printed or distributed electronically. Some modern digital guides, like the Google Earth User Guide, use a fluid structure with many internal links to help users navigate information quickly.
Modern manuals have changed significantly due to increasing product complexity. For instance, car owner's manuals have become much larger in recent years. This growth is partly due to more complex audio and navigation systems that require their own instructions. It is also driven by the need for extensive safety warnings to avoid product liability lawsuits. A typical car manual covers control locations, maintenance schedules, and technical specifications like fuel capacity.
Technological shifts have also changed how these guides are delivered to consumers. To save on manufacturing costs, some computer manuals are supplied on CD-ROMs. Other companies provide instructional videos on DVDs or videotapes to accompany the written text. Many businesses now offer free PDF copies of their manuals via their websites. Even the way we interact with manuals is changing through artificial intelligence. In 2017, IBM released Watson, which can help understand natural language. This follows trends like "Ask Mercedes," which allows drivers to use speech or text to get information from their vehicle.
