+# Heroku Playwright Buildpack
+
+This buildpack installs all the needed dependencies to use Playwright with Chromium and Firefox on Heroku.
+
+[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy?template=https://github.com/mxschmitt/heroku-playwright-example)
+
+## Usage
+
+For using this buildpack, you have to add the buildpack **before** installing your Node.js dependencies.
+
+```txt
+heroku buildpacks:set https://github.com/mxschmitt/heroku-playwright-example -a my-app
+```
+
+For a full example, see [here](https://github.com/mxschmitt/heroku-playwright-example) a usage with the Express library.
+
+## Best practises
+
+It's common to only install the [browser-specific NPM packages](https://playwright.dev/#version=v1.1.1&path=docs%2Finstallation.md&q=download-single-browser-binary), which will reduce installation time and slug size on Heroku in the end, that should fix also the error that the slug size is too large.
