“对应源代码” 是指生成、安装和(对于可执行作品)运行目标代码所需的所有源文件和与之关联的接口定义文件，以及控制这些活动的脚本，但不包括编译环境、编译工具、云服务平台（如果有）。
“分发” 是指通过任何媒介向他人提供“贡献”或“衍生作品”的行为，以及利用“贡献”或“衍生作品”通过网络远程给用户提供服务的行为，例如：通过利用“贡献”或“衍生作品”搭建的云服务平台提供在线服务的行为。
1. 授予版权许可
每个“贡献者”根据“本许可证”授予您永久性的、全球性的、免费的、非独占的、不可撤销的版权许可，您可以复制、使用、修改、“分发”其“贡献”或“衍生作品”，不论修改与否。

（2）如果您“分发”您接收到的“贡献”，您必须使用“本许可证”提供该“贡献”的源代码副本；如果您 “分发”您的“衍生作品”，您必须：
（i）随“衍生作品”提供使用“本许可证”“分发”的您的“衍生作品”的“对应源代码”。如果您通过下载链接提供前述“对应源代码”，则您应将下载链接地址置于“衍生作品”或其随附文档中的明显位置，有效期自该“衍生作品”“分发”之日起不少于三年，并确保接收者可以获得“对应源代码”；或者，
（ii）随“衍生作品”向接收者提供一个书面要约，表明您愿意提供根据“本许可证”“分发”的您“衍生作品”的“对应源代码”。该书面要约应置于“衍生作品”中的明显位置，并确保接收者根据书面要约可获取“对应源代码”的时间从您接到该请求之日起不得超过三个月，且有效期自该“衍生作品”“分发”之日起不少于三年。
5. 违约与终止
如果您违反“本许可证”，任何“贡献者”有权书面通知您终止其根据“本许可证”授予您的许可。该“贡献者”授予您的许可自您接到其终止通知之日起终止。仅在如下两种情形下，即使您收到“贡献者”的通知也并不终止其授予您的许可：
（1）您在接到该终止通知之前已停止所有违反行为；
（2）您是首次收到该“贡献者”根据“本许可证”发出的书面终止通知，并且您在收到该通知后30天内已停止所有违反行为。

7. 免责声明与责任限制
“贡献”在提供时不带有任何明示或默示的担保。在任何情况下，“贡献者”或版权人不对任何人因使用“贡献”而引发的任何直接或间接损失承担任何责任，不论该等损失因何种原因导致或者基于何种法律理论,即使其曾被告知有该等损失的可能性。
