How to

A how to is a set of instructions needed to complete a task or build something.

A how to should include:

• A brief overview of the project being built or end result of the instructions
• A list of materials, tools or prerequisites (if needed)
• Time needed
• Appropriate safety warnings (if needed)
• Instructions for the project
• What to do after the project is finished (cleanup)
• How to use the result or object constructed

A how to will almost always contain some degree of personal opinion in the form of helpful suggestions. This is acceptable within reasonable bounds.

See how-tos for a list of Wikipedia how-tos.
