-# Getting Start
+A demo project showcasing how to integrate Obsidian with Vite and SWC.
 
-Install `yalc` to troubleshoot
+## Running the project
+```bash
+yarn install
+yarn dev
+```
+Then open the app at `http://localhost:5173/`
 
-In the `swc-plugin-obsidian` run `yalc publish`
-
-Within the `vite-app` folder, run `yarn install`
-
-Run `yalc add [email protected]`
-
-Run `yarn dev` to spin up the project and open in browser at `http://localhost:5173/`
-
-Open the plugin inspector at `http://localhost:5173/__inspect/`
-
-## Running Tests
-
-There is a minimal test that can be run with `yarn test`. It will assert against the dom to check if the dependency was injected correctly.
+## Debugging
+To debug the SWC plugin, you can run `yarn dev:debug` which will open Chrome with the DevTools attached. Additionally, you can open the plugin inspector at `http://localhost:5173/__inspect/` to view the transpiled code.
 
 ## Notes
-
-The obsidian plugin is commented out by default in the `vite.config.ts` file.
-Uncomment this line and it's import to begin troubleshooting.
-
-## Known Issues
-
-The `obsidian` plugin interferes with the react plugin, which automagically imports `React` into any tsx files. So there is as compile error that the `React` import was not found. You can work around this by importing `React` in `main.tsx` but this shouldn't be necessary.
-
-The `obsidian` plugin seems to mangle _any_ ts and tsx file. Ideally, it should only mangle files with obsidian decorators.
+The app is using [unplugin-swc](https://github.com/unplugin/unplugin-swc) to configure SWC. It's a drop in replacement for [vite-plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) and supports the same functionality while providing a more flexible API.
