Put the main and most important ideas near the beginning

• the purpose of the material should be clear to the reader
• if you want your readers to do something, they need to
  know right away
• instructions must be explicit, not implicit
• consider highlighting the most important information, by
• using bold type, a box, or a different set-up
• repeat or summarize important facts or ideas

Use logical order based on the reader's needs

• start with information the reader is familiar with
• go from the known to the unknown
• build new ideas on old ideas
• go from the general to the specific
• give one new idea or piece of information at a time
• use chronological order when possible
