Tips:

• Remember to use the present tense
• Remember to write chronologically (the processes should be written about in the order they happen)
• Remember to use appropriate sequencers (first, then, next)
• Remember to write this in your own words (do not simply copy the words on the diagram)
• You do not need to mention all of the parts
