+# 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
+
+`cd samples/layer-data-quakes-red`
+`npm start`
+
+### Build an individual example
+
+`cd samples/layer-data-quakes-red`
+`npm run build`
+
+From 'samples':
+
+`npm run build --workspace=layer-data-quakes-red/`
+
+### Build all of the examples.
+
+From 'samples':
+
+`npm run build-all`
+
+### Run lint to check for problems
+
+`cd samples/layer-data-quakes-red`
+`npx eslint index.ts`
