I am writing an extension for google chrome, where to start?

Question

JavaScript

For study, I needed a dictionary in the form of a google chrome extension. It seems that everything is just a key (120 characters) value (250+). How to add data to the browser's local storage and how to do a dictionary search with output? I give in to myself, and the dictionary can be arranged in advance in any form and it remains just a search , and not on the go, those without adding. Who can tell how to implement this with a minimum of js, maybe there are some examples?
In my opinion, there have been many changes in the development of extensions, and you can’t keep track of everything.
