+# Bufstream quickstart
+
+This directory contains example code for Bufstream's basic quickstart.
+
+It set up a minio for S3 storage and a postgres instance that bufstream connects to,
+plus akhq for easy of exploration.
+
+Simply run:
+
+```
+$ docker compose up
+```
+
+And once AKHQ is ready, navigate to http://localhost:8080/ to create and explore topics.
+
+You can also access:
+
+* minio's admin interface at http://localhost:9001/
+* bufstream connect endpoint at http://localhost:8089/
+* bufstream kafka endpoint at http://localhost:9092/
