+# ScyllaDB
+
+ScyllaDB is a NoSQL database management system that is compatible with Apache Cassandra. 
+It is designed to scale linearly across multiple commodity servers, while maintaining low latency and high availability. 
+ScyllaDB is written in C++ and uses the Seastar framework for concurrency and asynchronous I/O.
+
+
+## Prerequisites

+**Cluster Status:**
+
+run `docker-compose exec scylladb-master nodetool status` to view the cluster status.
+
+```go
