+# Google Maps JavaScript Sample
+
+This sample is generated from @googlemaps/js-samples located at
+https://github.com/googlemaps-samples/js-api-samples.
+
+## Setup
+
+### Before starting run:
+
+`npm i`
+
+### Run an example on a local web server
+
+First `cd` to the folder for the sample to run, then:
+
+`npm start`
+
+### Build an individual example
+
+From `samples/`:
+
+`npm run build --workspace=sample-name/`
+
+### Build all of the examples.
+
+From `samples/`:
+
+`npm run build-all`
+
+## Feedback
