more tutorial on InDesign ! 

learnt how to put in tabs, indents and create paragraph styles for easier editing; save&keep everything (images, fonts etc) into 1 folder by packaging it; export high res & low res pdf for different purposes (high res has way better quality but bigger file size)

the summary info bit from packaging the document is really useful, lists out all the pieces used on the indd file so you can double-check everything clearly before exporting it for printing/publishing
