-## Preparing for rollbar.js tests

-(For rollbar.js maintainers)
-
-Rollbar.js test automation includes tests that load and exercise this example app.
-For those tests to work, main.js must be available and up to date in ./examples/webpack/dist/.
-If the example app has changed or changes to rollbar.js need to be pulled in,
-update and commit a new main.js.
-
-```
-# Build the rollbar.js dist if needed.
-npm run build
-
-# Prepare the example's npm bundle.
-cd examples/react && npm install
-
-# Build the output files.
-npm run build
-
-# The rollbar.js dist is no longer needed, and can be reverted.
-cd ../.. && git checkout dist

+## For rollbar.js maintainers

+`dist/` is not committed. CI's `npm run validate:examples` installs and builds
+this example against the current SDK, which checks that webpack 4 still resolves
+`rollbar/replay` through `replay/package.json`.
+
+The production build uses an absolute `publicPath`,
+`/examples/react-replay-webpack4/dist/`, because `loadHtml` in
+`test/util/fixtures.ts` recreates a page's scripts inside the test runner's
+page, where a relative path would resolve against the wrong URL. Because `dist/`
+is not committed, a browser test that loads this build would also need CI to
+build the example before the browser tests run.
