Instruction manuals come in various forms. Generally speaking, based on the product they explain, they can be categorized as follows: product manuals, user manuals, installation manuals, and theatrical performance manuals, etc.
Product Manuals: Product manuals primarily refer to instructions for everyday production and consumer products. They mainly introduce all aspects of a product, such as its constituent materials, performance, storage methods, precautions, and main uses. These manuals can be for manufactured consumer goods, such as televisions, or for everyday consumer goods, such as food and medicine.
User Manuals: User manuals introduce specific methods and procedures for using a product. See the example "Shaver Instruction Manual."
Installation Manuals: Installation manuals mainly explain how to assemble a set of disassembled product parts into a usable, complete product. We know that many products are disassembled and packaged for ease of transportation. Therefore, after purchasing the product, the user needs to properly assemble the disassembled parts. This requires a detailed and specific installation instruction in the product manual. Example: "CD-ROM Drive Installation."
A theatrical performance brochure is a rather informal brochure. Its main purpose is to introduce the main plot of the play or film, and also to recommend the performance to the audience. For large-scale performances, introductions to the cast and crew, program descriptions, etc., are also used as promotional texts to attract more audiences.
