+### Hot Reload Support
+
+Hot reload for serverless-esbuild and serverless-plugin-typescript are available with extra configuration.
+
+The watch/reload mechanism is available form serverless-webpack, but is disabled by default for esbuild and typescript.
+
+The flag "watchReload: true" will turn on the watcher so that typescript and esbuild solutions use the watcher to hot reload the handlers.
+The path to the built handlers must be specified for the watcher to work correctly.
+
+example:
+```yaml
+custom:
+  offlineEdgeLambda:
+	path: '.esbuild/service'
+	watchReload: true
+```
+
+Additional options can be used to modify the behavior of the file watcher and debounce logic (ignoreInitial, awaitWriteFinish, interval, debounce, and any other chokidar option).
+
+example:
+
+```yaml
+custom:
+  offlineEdgeLambda:
+	path: '.dist/service'
+	watchReload: true
+	ignoreInitial: true
+	awaitWriteFinish: true
+	interval: 500,
+	debounce: 750
+```
