 - To comply with the code style, **you need to run the `format` script**
+- To lint the code, **you need to run the `lint:fix` script**
 - To transpile source code to `javascript` we use [NCC](https://github.com/vercel/ncc). **It is very important to run the `build` script after making changes**, otherwise your changes will not get into the final `javascript` build
