When creating an installation guide for a swing set, which of the following must be included in the introduction?

Including assembly instructions and a time estimate in the introduction of an installation guide for a swing set is essential because it sets clear expectations for the users right from the start. The introduction serves to provide the user with a roadmap for what to expect throughout the installation process. By outlining these key elements upfront, the user can quickly gauge the complexity of the assembly and how long the task might take, helping them to prepare adequately in advance.

Assembly instructions outline the specific steps that will be detailed later in the guide, ensuring that the user understands what they will need to do. A time estimate helps in planning, allowing users to allocate adequate time for completing the assembly without feeling rushed or overwhelmed. This information is crucial for enhancing user experience and ensuring that the installation is completed correctly and efficiently.

While local building regulations, warranty information, and promotion of other products may be valuable in other sections of the guide, they do not directly inform the user about the immediate task of installation in the introduction. Thus, they do not serve the primary purpose of preparing the user for assembly.
