+# HTTP GET Arrow Data: Simple Ruby Server Example
+
+This directory contains a minimal example of an HTTP server implemented in Ruby. The server:
+1. Creates a list of record batches and populates it with synthesized data.
+2. Listens for HTTP GET requests from clients.
+3. Upon receiving a request, sends an HTTP 200 response with the body containing an Arrow IPC stream of record batches.
+
+To run this example:
+
+```sh
+bundle install
+bundle exec rackup --port=8008
+```
