-**Make requires tab characters instead of 4 spaces in the second line. Make sure you're using a tab character when pasting this into the file**
+Now when you use `devenv up` to start the IHP dev server, the TailwindCSS build process will be started as well. The `--watch=always` flag forces `tailwindcss` to always stay running and watch for any CSS changes in your project and rebuild the `static/app.css` file as needed.
 
-This defines a new command `make tailwind-dev` that runs `npx tailwindcss build` whenever a CSS file inside the `tailwind/` directory changes. The CSS output will be placed at `static/app.css` (the standard main CSS file of IHP apps). It will use the tailwind configuration at `tailwind/tailwind.config.js`.

-## Developing with Tailwind
-
-Once everything is installed, you can start your tailwind build by calling:
-
-```bash
-make tailwind-dev

-
-Whenever you change any CSS file in `tailwind/` it will automatically rebuild your styles and write it to `static/app.css`.

 ## Building for production
 
 Because we defined the `static/app.css` make task above, the standard process of building IHP CSS applies here as usual:
