Here we are—your project is set up and ready to go. You’ll notice many files and folders, so let me walk you through them from bottom to top,

• tsconfig.json: This is the configuration file for TypeScript. It defines what should be type-checked, ignored and the rules to follow.
• tailwind.config.ts: This is where TailwindCSS is configured. You can extend TailwindCSS by customizing colors, sizes, shadows, plugins, or anything else you need.
• README.md: A simple markdown file that explains how to run the project and provides relevant information.
• postcss.config.mjs: It’s a configuration file for PostCSS, a tool used to process CSS with various plugins. You can see here that it mentions tailwindcss as a plugin, which allows you to use its utility first classes in your project.
• package-lock.json: It’s a file that locks the versions of dependencies and their sub-dependencies, ensuring that everyone working on the project uses the exact same versions
• package.json: It has all project dependencies and scripts. (explain some of these main scripts by showing/reading descriptions from here)
• next-env.d.ts: It’s a typescript declaration file for Next.js. And as said here, you shouldn’t modify or put your typescript types here. It’s specifically for Next.js
• next.config.ts: This file allows you to configure Next.js features, such as experimental options, image settings, build settings, and others.
• .gitignore: For Git files and folders to ignore
• .eslintrc.json: For configuring ESLint
• public: A place for static assets. Always put your images and other static data here
• node_modules: You know, it’s the heaviest object in the universe

Jokes aside, it’s a folder containing all the dependencies (packages) code required to run this application.

And finally, the most important folder is the app folder, which we’ll explore next,
