+### Editor Integration
 
 Integrating shadow-cljs with your editor helps tremendously with development. After having run `npm run dev` as described above you can connect to the REPL and get features like in-editor code execution and code completion / documentation lookup. For further information see [this part of the shadow-cljs user guide](https://shadow-cljs.github.io/docs/UsersGuide.html#_editor_integration). Recommended editors and plugins are Calva for VSCode and CIDER for Emacs (comes with Spacemacs). Make sure to open `localhost:8080` in the browser after starting the `dev:cljs` task to execute ClojureScript code in a live REPL.

+This project uses [karma](https://karma-runner.github.io/) for tests. There is a check inside `karma.conf.js` to see whether Firefox is installed (via `which firefox` which probably breaks on Windows 🤷); if that command doesn't fail it will be used as the test runner. Otherwise Chrome will be used. If you have Chromium installed, make sure to set the `CHROME_BIN` environment variable to point to Chromium.
