 luban是一个通用型对象生成与缓存方案, 在此基础上实现了一个功能**完备强大灵活易用**的 **游戏配置解决方案**。
 
-luban最初为无缝开放世界MMORPG这样的超大型项目而设计，擅长处理大型复杂的配置数据和结构，也适合向下用于卡牌、回合制、SLG等中轻度游戏。
-
-luban基于 **meta定义 + 数据源** 的设计，实现了**完备的类型系统**，增强了excel格式，同时提供json、xml、lua等多种数据源支持，统一了数据定义、加载、检验、数据导出及代码生成的游戏配置Pipeline，彻底解决了中大型项目中难以在excel中配置复杂数据以及一个项目中excel、json等多种的配置方案并存的问题。
+luban基于 **meta定义 + 数据源** 的设计，实现了**完备的类型系统**，增强了excel格式，同时提供json、xml、lua等丰富的数据源支持。既可以处理常规的简单配置，也完美处理**AI、技能、副本**等复杂配置，真正实现了统一数据定义、加载、检验、数据导出及代码生成的游戏配置工作流，彻底解决了中大型项目中需要程序员手动处理复杂配置的问题。
 
 Luban生成过程极快。对于普通的导表工具，一个典型的MMORPG项目后期全量生成配置往往需要几十秒。Luban使用client/server的云生成模型，通过多线程并发生成+对象缓存机制，大多数情况下可以1s内完成整个生成过程。
