## Install

This extension can be installed via official web store or manually, via the artifacts published in the release page.
Consider that installing via web store is the recommended way, as it will automatically update the extension when a new
version is released.

> [!NOTE]
>
> Since publishing extensions on the web store requires approval, the latest version on the web store may mismatch the
> latest version on the GitHub repository.

## Project structure

The project structure is organized in a monorepo using pnpm workspaces. The structure is still WIP and doesn't 
respect yet the best practices (root folder is a package itself too), but it will be improved in the future.

- **brand**: contains the branding assets, such as logos, promotional assets published in web store.
- **markdown-schema**: a package that contains the markdown proseMirror nodes used by the editor.
- **markdown-transformer**: a package that contains the logic to transform the markdown schema into ProseMirror and vice
  versa.
- **extension**: the browser extension package, responsible to load the editor in the GitHub pages.
- **src**: the core of the editor
