+## Repository Structure
+
+There's both a `listings` and a `pages` directory in the repository. The `listings` directory contains all the Cairo programs used in the book, while the `pages` directory contains the Markdown files that make up the book's content.
+The whole repository is a Next.js project, and the `listings` directory is a scarb project.

 - Do not write directly Cairo program inside the markdown files. Instead, use code blocks that import the Cairo programs from the `listings` directory. These programs are bundled into scarb projects, which makes it easier to test and build all programs. See the next section for more details.

 ## Adding a new Cairo program
 
 You can add or modify examples in the `listings` directory. Each listing is a scarb project.

+You can use `scarb init` to create a new scarb project, but be sure to remove the generated git repository with `rm -rf .git` and follow the instructions below for the correct `Scarb.toml` configuration.
 
 You can choose to use standard cairo with `cairo-test` or Starknet Foundry with `snforge_std`.
 Please use the appropriate `Scarb.toml` configuration. `scarb test` will automatically resolve to `snforge test` if `snforge_std` is in the dependencies.
