## About WXT - Browser Extension Framework

This is help for building browser extensions with WXT. The framework organises a project by its entry points as files, builds with Vite, and pulls in imports for you, so setting up the plumbing is not the first thing you do.

It covers storage that is typed and can be migrated when your data shape changes, interfaces that live inside the pages people are browsing, and support for both MV2 and MV3 across multiple browsers.
