I am brand new to Zotero development and new to node, but I am working on a patch for the reader to give me more flexibility in filtering annotations. I have successfully followed the instructions and built Zotero from source (https://www.zotero.org/support/dev/client_coding/building_the_desktop_app) with a caveat: changes that I made inside `reader/` are not reflected in the application that is built when I execute `app/scripts/build_and_run -r`.

As a basic example: (1) I can edit html content in `chrome/content/zotero/` and see those changes reflected when I build the app. (2) but when edit html content in `reader/src/common/components/sidebar/annotations-view.js` nothing changes when I build the app (I can actually delete the contents of this file with no effect).

What is the intended procedure for developers working on the reader to build Zotero?

Thank you for your help!
