+title: Files and folder structure
+order: 110
+---
+
+Inside our `tutorial` folder, the `design/src` folder holds the source code for
+the new pattern we will create.
+
+If you want to support internationalization in your design, your translations 
+go in the `design/i18n` folder. 
+
+We can safely ignore all other files and folders, as they are part of the
+FreeSewing development environment.
+So feel free to skip ahead to [Our first part](/tutorials/pattern-design/our-first-part).
+
+## Notes
+
+If you'd like to learn about those other files and folders, here's what they do:
+
+### folders

+- `design`: Holds the source code for our design
+- `lab`: Holds [React][react] hooks and components specific to the development environment
+- `node_modules`: Holds installed dependencies
+- `pages`: Holds [NextJS][next] client-side routes, aka pages
+- `public`: Holds pre-generated translation files
+- `shared`: Holds files from FreeSewing's shared codebase for frontend development
+
+### files
+
+- `next.config.mjs`: The [NextJS][next] configuration file
+- `next-i18next.config.js`: The configuration file for [next-i18next][i18n] which handles translation within NextJS
+- `package.json`: Every Node.js project has a [package.json][pkg] file which holds important metadata and lists dependencies
