 - Schema Metadata Management, including VertexLabel, EdgeLabel, PropertyKey and IndexLabel
 - Multi-type Indexes, supporting exact query, range query and complex conditions combination query
-- Plug-in Backend Store Driver Framework, support `RocksDB`/`HStore`, `HBase`, `Cassandra/ScyllaDB`, and `MySQL/Postgre` now and easy to add another backend store driver if needed
+- Plug-in Backend Store Framework, mainly support `RocksDB`/`HStore` + `HBase` for now and you could choose other backends in the [legacy version](https://hugegraph.apache.org/docs/download/download/) ≤ `1.5.0` (like `MySQL/PG`/`Cassandra` ...)
 - Integration with `Flink/Spark/HDFS`, and friendly to connect other big data platforms
+- Complete graph ecosystem (including both in/out-memory `Graph Computing` + `Graph Visualization & Tools` + `Graph Learning & AI`, see [here](#3-build-from-source))
