reboundstudent-san,
I will answer your question but please in the future create a new thread rather than using an existing thread to ask a question. Only because it makes it easier for people to find when searching the forum if they have a similar question and it also allows the thread opener to be able to focus on their question specifically. Thanks

In regards to 通りに. it does mean "just" in the sense of "just as I do". 通りに is used in situations where one is to copy what they have seen or heard exactly.
There are a number of uses:
1. V1通りにV2 (Dictionary Form, た form or Nの)
"This means copy exactly in words or actions (V2) what one has heard seen read learnt etc (V1)."
僕がやるとおりにやってください。
Please do as I do
2. Nの通りにV
"This means that an action (V) is done in accordance with the manner shown by the preceding phrase."
線のとおりに紙を切ってください。
