README.md not clear enough

Hello @pgjaiganesh,

I'm quite new to AWS and i need to understand this work.
In the README.md on the second step you said that "A new bucket of format {CODE_BUCKET}-us-east-1 is created which holds the code assets for deployment." I don't understant what do you mean by "the code assets for deployment".

Ty for all your work and help

Have a nice day !
Best regards :)

阅读 README.md 中的第二步，尤其是描述 {CODE_BUCKET}-us-east-1 bucket 的句子。为使用此 AWS 示例的新手澄清“用于部署的代码资产”是什么意思，然后确认修改后的措辞说明了 bucket 中包含什么，以及为什么要创建它。
