+
+- https://speakerdeck.com/mizdra/css-modules-kit
+
+## Repo Setup
+
+```console
+npm install
+npm run test
+```
+
+## npm-scripts
 
 - `npm run build`: Build for production
-- `npm run dev`: Run for development
 - `npm run lint`: Run static-checking
 - `npm run test`: Run tests
 
+## How to debug
+
+You can run code in debug mode from the "Run and Debug" panel in VS Code. To start debugging, select one of the following configurations.
+
+- `codegen (...)`: Debug for `codegen` package
+- `eslint-plugin (...)`: Debug for `eslint-plugin` package
+- `stylelint (...)`: Debug for `stylelint` package
+- `vscode (...)`: Debug for `vscode` and `ts-plugin` package
+- `vscode-test`: Debug for `npm run test:vscode`
+
+Good to know:
+
+- You can set breakpoints in `*.ts` files.
+- In VS Code, you can view the tsserver log with `F1 > TypeScript: Open TS Server log`.
+  - Runtime errors from `ts-plugin` are output there.
+- In VS Code, you can view the Extension Host log with `F1 > Output: Show Output Channels... > Extension Host`.
+  - If the extension fails to load, the log will be output there.
+
+## Pull Request Guidelines
+
+1. Write your code
+1. Add tests if necessary
+1. Update documentation if necessary
+1. Pass `npm run lint` and `npm run test`
+1. Run `npx @changesets/cli add` to create a changeset if the change affects users
+   - The summary should be in the following format:
+     - For bug fixes: `fix: ...`
+     - For new features: `feat: ...`
+     - For dependency updates: `deps: ...`
+     - For everything else: `chore: ...`
+1. Create a pull request
+
+Good to know:
+
+- There are no rules for commit messages. Write whatever you like!

 By default, CSS Modules have limited language features in editors. For example:
 
-- Clicking on `styles.button` does not jump to its definition in `Button.module.css`.
-- When renaming `styles.button`, the corresponding `.button {...}` in `Button.module.css` is not renamed.
-- Performing "Find All References" on `styles.button` does not find its definition in `Button.module.css`.
+- Clicking on `styles.button` does not go to its definition in `Button.module.css`.
+- Renaming `styles.button` does not rename the corresponding `.button {...}` in `Button.module.css`.
+- Find all references of `styles.button` does not include its definition in `Button.module.css`.
 
-It has been difficult to solve these issues because the TypeScript Language Server (tsserver) does not handle CSS files. Since tsserver does not hold information about CSS files, it cannot calculate jump destinations or determine which code should be renamed.

-Additionally, css-modules-kit provides various development tools for CSS Modules, such as a stylelint plugin and a utility for generating `*.d.ts` files.
+Another method that provides rich language features is to use the VS Code Extension API (see: https://github.com/Viijay-Kr/react-ts-css). However, it only supports VS Code. On the other hand, css-modules-kit is based on the TypeScript Language Service Plugin, so it supports other editors as well.
