+## Overview
 
-![redis-shake2.PNG](https://s2.loli.net/2022/07/10/OZrSGutknlI8XNp.png)
+RedisShake is a tool designed for processing and migrating Redis data. It offers the following features:
 
-![image.png](https://s2.loli.net/2022/06/30/vU346lVBrNofKzu.png)
+1. **Redis Compatibility**: RedisShake is compatible with Redis versions ranging from 2.8 to 7.2, and supports various
+   deployment methods including standalone, master-slave, sentinel, and cluster.
+
+2. **Cloud Service Compatibility**: RedisShake works seamlessly with popular Redis-like databases provided by leading
+   cloud service providers, including but not limited to:
+    - [Alibaba Cloud - ApsaraDB for Redis](https://www.alibabacloud.com/product/apsaradb-for-redis)
+    - [Alibaba Cloud - Tair](https://www.alibabacloud.com/product/tair)
+    - [AWS - ElastiCache](https://aws.amazon.com/elasticache/)
+    - [AWS - MemoryDB](https://aws.amazon.com/memorydb/)
+
+3. **Module Compatibility**: RedisShake is compatible
+   with [TairString](https://github.com/tair-opensource/TairString), [TairZSet](https://github.com/tair-opensource/TairZset),
+   and [TairHash](https://github.com/tair-opensource/TairHash) modules.
+
+4. **Multiple Export Modes**: RedisShake supports PSync, RDB, and Scan export modes.
+
+5. **Data Processing**: RedisShake enables data filtering and transformation through custom scripts.
+
+## Getting Started
+
+### Installation
+
+#### Download the Binary Package
+
+Download the binary package directly from the [Releases](https://github.com/tair-opensource/RedisShake/releases) page.
+
+#### Compile from Source
+
+To compile from source, ensure that you have a Golang environment set up on your local machine:
+
+```shell
+git clone https://github.com/alibaba/RedisShake
+cd RedisShake
+sh build.sh
+```
+
+### Usage
+
+Assume you have two Redis instances:
+
+* Instance A: 127.0.0.1:6379
+* Instance B: 127.0.0.1:6380
+
+Create a new configuration file `shake.toml`:
+
+```toml
+[sync_reader]
+address = "127.0.0.1:6379"
+
+[redis_writer]
+address = "127.0.0.1:6380"
+```
+
+To start RedisShake, run the following command:
+
+```shell
+./redis-shake shake.toml
+```
+
+For more detailed information, please refer to the documentation:
+
+- [中文文档](https://tair-opensource.github.io/RedisShake/)
+- [English Documentation](https://tair-opensource.github.io/RedisShake/en/)
+
+## Contributing
+
+We welcome contributions from the community. For significant changes, please open an issue first to discuss what you
+would like to change. We are particularly interested in:
+
+1. Adding support for more modules
+2. Enhancing support for Readers and Writers
+3. Sharing your Lua scripts and best practices
+
+## History
+
+RedisShake is a project actively maintained by the [Tair team](https://github.com/tair-opensource) at Alibaba Cloud. Its
+evolution can be traced back to its initial version, which was forked
+from [redis-port](https://github.com/CodisLabs/redis-port).
+
+During its evolution:
+
+- The [RedisShake 2.x](https://github.com/tair-opensource/RedisShake/tree/v2) version brought a series of improvements
+  and updates, enhancing its overall stability and performance.
+- The [RedisShake 3.x](https://github.com/tair-opensource/RedisShake/tree/v3) version represented a significant
+  milestone where the entire codebase was completely rewritten and optimized, leading to better efficiency and
+  usability.
+- The current version, [RedisShake 4.x](https://github.com/tair-opensource/RedisShake/tree/v4), has further enhanced
+  features related to readers, configuration, observability, and functions.

+
+## 历史
+
+RedisShake 是阿里云 [Tair 团队](https://github.com/tair-opensource)
+积极维护的一个项目。它的演变可以追溯到其初始版本，该版本是从 [redis-port](https://github.com/CodisLabs/redis-port) 分支出来的。
+
+版本（不同版本间配置不通用）：
+
+- [RedisShake 2.x](https://github.com/tair-opensource/RedisShake/tree/v2) 版本带来了一系列的改进和更新，提高了其整体稳定性和性能。
+- [RedisShake 3.x](https://github.com/tair-opensource/RedisShake/tree/v3) 版本是一个重要的里程碑，整个代码库被完全重写和优化，具有更好的效率和可用性。
+- [RedisShake 4.x](https://github.com/tair-opensource/RedisShake/tree/v4) 版本
+  ，进一步增强了 [Reader](../reader/scan_reader.md)、配置、可观察性和 [function](../function/introduction.md) 相关的特性。

+# 迁移模式选择
+
+目前 RedisShake 有三种迁移模式：`PSync`、`RDB` 和
+`SCAN`，分别对应 [`psync_reader`](../reader/psync_reader.md)、[`rdb_reader`](../reader/rdb_reader.md)
+和 [`scan_reader`](../reader/scan_reader.md)。这三种模式各有适合的场景，本文根据场景特点介绍如何选择。

+# rdb_reader
+
+## 介绍
+
+可以使用 `rdb_reader` 来从 RDB 文件中读取数据，然后写入目标端。常见于从备份文件中恢复数据。
+
+## 配置
+
+```toml
+[rdb_reader]
+filepath = "/tmp/dump.rdb"

+# Scan Reader
+
+## 介绍
+
+当源端数据库不兼容 PSync 协议时，推荐使用 `scan_reader`。
+
+优势：兼容性好，只要源端数据库支持 `SCAN` 与 `DUMP` 命令，就可以使用 `scan_reader`。
+
+劣势：
+
+1. 数据一致性不如 [`sync_reader`](./sync_reader.md)。
+2. `SCAN` 命令与 `DUMP` 命令会占用源端数据库较多的 CPU 资源
+
+## 配置
+
+```toml
+[scan_reader]
+cluster = false
+address = "127.0.0.1:6379" # when cluster is true, address is one of the cluster node
+username = ""              # keep empty if not using ACL
+password = ""              # keep empty if no authentication is required
+tls = false
+ksn = false
+```
+
+默认情况下，RedisShake 会使用 `SCAN` 命令来遍历一遍所有的 Key，分别使用 `DUMP` 与 `RESTORE` 命令来从源端读取 Key
+的内容，并写入目标端。Redis 的 SCAN 命令只保证 SCAN 的开始与结束之前均存在的 Key 一定会被返回，但是新写入的 Key 有可能会被遗漏。
+
+如果需要提高数据一致性，可以开启 `ksn` 参数，这样 RedisShake 会在 `SCAN`
+之前使用 [Redis keyspace notifications](https://redis.io/docs/manual/keyspace-notifications/)
+能力来订阅 Key 的变化。当 Key 发生变化时，RedisShake 会使用 `DUMP` 与 `RESTORE` 命令来从源端读取 Key 的内容，并写入目标端。
+::: warning
+Redis keyspace notifications 不会感知到 `FLUSHALL` 与 `FLUSHDB` 命令，因此在使用 `ksn` 参数时，需要确保源端数据库不会执行这两个命令。

+# Sync Reader
+
+## 介绍
+
+当源端数据库兼容 PSync 协议时，推荐使用 `sync_reader`。兼容 PSync 协议的数据库有：
+
+* Redis
+* Tair
+* ElastiCache 部分兼容
+* MemoryDB 部分兼容
+
+优势：数据一致性最佳，可以实现不停机的切换
