Summarize this article in one sentence.
Effective instruction is simple. Don't use long, involved paragraphs. Instead, use short, clear sentences, bullet points, and visual aids. Instructions should be full of active, descriptive words. Start your steps with action verbs. This gives the reader a clear action to perform. Each step should read as a command and use the imperative mood.  When defining or explaining, use as much descriptive language as possible. For example, say "Add two eggs" instead of "Two eggs should be added to the cake mix." When you include additional information, make sure that you are including only what is necessary. Ask yourself, "Does the reader need to know this definition to understand the instructions?" or "Does the reader need this tip to successfully complete this task?" Refrain from adding unnecessary information. Unneeded definitions, tips, steps, or information can confuse your readers, making it difficult to follow the instructions. When writing instructions, you should address the reader. Do this using the word "you." This helps lead the reader personally through the steps. When writing instructions, be as specific as possible. Outline exactly what they do. This includes which way they turn a wrench, how many feet they walk, or what the consistency of the cake should look like when they are done.  Give all measurements exactly. If someone needs to cut off 5/8-inch of a board, say that. For example, if you are baking a cake, don't wait until step 4 to say, "Before mixing the ingredients, sift the flour and bring the eggs to room temperature." Transitions help connect the steps to each other. They also help relate the ideas. In instructions, you will use sequence and time transitions. This helps the reader understand the step-by-step instructions. Some common transitions are: first, next, then, finally, after, before.

Summary:
Keep it simple. Use active words. Add only necessary information. Address the reader. Be specific. Use sequence and time transitions.
