+# TSConfig Aliases
+
+Purpose
+- Add `paths` and `baseUrl` to `tsconfig.json` and document the steps to wire the aliases to tooling (Vite, Vitest/Jest, ESLint, IDEs).
+
+Example prompts
+- "create tsconfig paths for @/components, @/utils"
+- "make imports use @/ alias and configure Vite"
+
+Output
+- Suggested `tsconfig.json` patch and example `paths` mapping.
+
+Example tsconfig snippet
+```json
+{
+  "compilerOptions": {
+    "baseUrl": "./",
+    "paths": {
+      "@/*": ["src/*"],
+      "@components/*": ["src/components/*"]
+    }
+  }
+}
+```
+
+Wiring notes
+- Add `vite-tsconfig-paths` to Vite plugins or set the same aliases in `vite.config.ts`.
+- For ESLint resolver, add `eslint-import-resolver-typescript` to `settings.import/resolver`.
+- Update IDE settings if necessary (VSCode uses tsconfig by default).
+
+Common pitfalls
+- Ensure `baseUrl` is set (often `.`) and that path globs match the file layout.
+- Restart the TypeScript server in the editor after changes.
