+修改说明
+------------
 
+由于原yiisoft/yii2-bootstrap5需要bower-asset/bootstrap，
 
-Installation
+而[asset-packagist](https://asset-packagist.org/package/bower-asset/bootstrap)上意外缺失了bower-asset/bootstrap最新版本(5.3.x)，
+
+现在手动在composer.json添加bower-asset/bootstrap 5.3.x版本会出现错误，
+
+我的项目需要使用bootstrap 5.3新增加的夜间模式，
+
+所以我将原包修改了一下，将依赖的bower-asset/bootstrap改为npm-asset/bootstrap，
+
+安装
