+### Node 10 with `asnc` handler
+
+1. Prepare function code
+
+```
+mkdir example-lambda-nodejs
+cd example-lambda-nodejs
+cat > handler.js <<EOF
+async function justWait() {
+  return new Promise((resolve, reject) => setTimeout(resolve, 100));
+}
+
+module.exports.sayHelloAsync = async (event) => {
+  await justWait();
+  return {hello: event.name};
+};
+EOF
+
+node -e "require('./handler').sayHelloAsync({}).then(h => console.log(h))"
+```
+
+2. Install node-10.x buildtemplate
+
+```
+tm deploy buildtemplate -f https://raw.githubusercontent.com/triggermesh/knative-lambda-runtime/master/node-10.x/buildtemplate.yaml
+```
+
+3. Deploy function
+
+```
+tm deploy service node-lambda -f . --build-template knative-node10-runtime --build-argument HANDLER=handler.sayHelloAsync --wait
