 # dts-css-modules-loader
 A small Webpack loader to generate typings for your CSS-Modules. Created as a replacement for the frozend [typings-for-css-modules-loader](https://github.com/Jimdo/typings-for-css-modules-loader). This loader does not make any changes in content of styles, just creates `*.d.ts` file during the work. It is assumed that the content will be preprocessed first by [css-loader](https://github.com/webpack-contrib/css-loader).
 
+### ⚠ BREAKING CHANGES
+
+* Since version 2.x only supports `webpack` version is `5`
+
 ## Installation
 ```bash
 npm i -D dts-css-modules-loader
