Some actions Juan can do to improve his list is to make the steps as concise as possible, use images if necessary and organize the steps appropriately.
<h3>What is a list?</h3>
Lists are common types of texts used to organize a set of elements of the same category. Some examples include:
Shopping lists are used by people to remember what to buy.
Instructions or text that explain how to complete a process by following steps.
<h3>How to improve the list?</h3>
Instruction's lists can be improved through the following:
Write steps concisely: Lists should be clear and direct this means avoiding words that are not necessary or that can confuse the reader.
Use images: Many instructions will require images and they help the reader to understand how to complete a process. For example, to explain to someone how to use a microwave for the first time you need to add an image that shows the buttons of the microwave.
Organize the steps: The steps should be organized sequentially to make the process clear for the reader.
Note: This question is incomplete because the list is not given; due to this, I answered it based on general knowledge.
