+## Motivation
+
+If you are a developer using multiple types of databases in your application and are considering deploying both your application and databases on K8s for cost or efficiency reasons, you will need to find suitable operators for each database. Learning the different operators and their APIs will introduce a significant learning curve and time costs, not to mention the effort required to maintain them.
+
+We aim to use a unified set of APIs (CRDs) and code to manage various databases on K8s. For example, we can use the `Cluster` resource to create a PostgreSQL cluster, a Redis cluster, or a Kafka cluster. This abstraction and unified API allow us to further use a single set of operator code to manage multiple types of databases, as well as handle day-2 operations, theoretically extending to any type of database engine.

 ## What is KubeBlocks
 
-KubeBlocks is an open-source control plane software that runs and manages databases, message queues and other data infrastructure on K8s. The name KubeBlocks is inspired by Kubernetes and LEGO blocks, signifying that running and managing data infrastructure on K8s can be standard and productive, like playing with LEGO blocks. 
+KubeBlocks is an open-source control plane software that runs and manages multiple popular database engines on K8s through a unified set of code and APIs. The core of KubeBlocks is a K8s operator, which defines a set of CRDs to abstract the common attributes of various database engines and uses these abstractions to manage the engine's lifecycle and day-2 operations.
 
-KubeBlocks could manage various type of engines, including RDBMSs (MySQL, PostgreSQL), Caches(Redis), NoSQLs (MongoDB), MQs(Kafka, Pulsar), and vector databases(Milvus, Qdrant, Weaviate), and the community is actively integrating more types of engines into KubeBlocks. Currently it has supported 32 types of engines.
+KubeBlocks could manage various type of stateful engines, including RDBMSs (MySQL, PostgreSQL), Caches(Redis), NoSQLs (MongoDB), MQs(Kafka, Pulsar), vector databases(Milvus, Qdrant, Weaviate), and data warehouses(ClickHouse, ElasticSearch, OpenSearch, Doris, StarRocks). Adding support for a new engine to KubeBlocks can be achieved by writing a KubeBlocks Addon. The community is actively integrating more types of engines into KubeBlocks, and it currently supports 35 types of engines.
 
-The core of KubeBlocks is a K8s operator, which defines a set of CRDs to abstract the common attributes of various engines. KubeBlocks helps developers, SREs, and platform engineers deploy and maintain dedicated DBPaaS, and supports both public cloud vendors and on-premise environments.
+The name KubeBlocks is inspired by Kubernetes and LEGO blocks, signifying that through the KubeBlocks API, adding, composing and managing database engines on K8s can be easy, standard and productive, like playing with LEGO blocks.
 
 ### Why you need KubeBlocks
 
-KubeBlocks integrates the most popular database/message-queue/data-processing engines and provides rich management functions, along with declarative APIs, on various environments. Furthermore, KubeBlocks offers the following benefits:
+KubeBlocks integrates the most popular database engines and provides rich management functions, along with declarative APIs, on various environments. Furthermore, KubeBlocks offers the following benefits:
 
-* Cost-effective
-  
-  KubeBlocks optimizes the kernel and parameters of MySQL and PostgreSQL databases for containerized and cloud environments, and its performance exceeds that of RDS with the same hardware (see our blogs for test reports).
+* Production-level
+
+  KubeBlocks has already been adopted by large internet companies, private clouds, the financial industry including banks and securities firms, telecom industry, the automotive industry, and SaaS software providers.
 
 * Reliability
-
-  KubeBlocks supports high-availability cluster configurations for multiple database engines, and supports Raft replication cluster for MySQL to achieve enhanced availability with durability guarantees.
+
+  KubeBlocks supports the integration of various mature high-availability best practices, such as Orchestrator, Patroni, and Sentinel. KubeBlocks also supports full backups, continuous backups, and point-in-time recovery (PITR).
+
+* Ease of use
+
+  KubeBlocks not only provides a YAML-based API but also offers an interactive kbcli tool to further simplify usage as a complement to kubectl. For example, you can install KubeBlocks and launch a playground environment on a desktop or cloud with a single command.
 
 * Observability
-  
+
   KubeBlocks collects monitoring metrics from richful data sources, integrates with the Prometheus stack, and provides insightful Grafana templates. In addition, troubleshooting tools such as slow logs are also provided.
 
 * Extensibility
-  
+
   KubeBlocks provides the addon mechanism for integrating new engines. So it can be extended to run the databases your project needs.
